    Trim the long branch pictured to match the others, so the outer canopy looks even. You want to leave as much photosynthetic material on as possible but not something that will snap off in a storm. Also, loosen those ties. The tree needs to move when the wind blows, just not blow over. Trees grow in response to stimulation. Moving in the wind will give it a stronger trunk and root system.

    Well, I certainly do! Being able to descend smoothly, with one hand, on a non-moving rope, is number one on the list of what a good multisender must be able to accomplish. Conversely, going up it is doing nothing and just needs to stay out of your way and grab quickly when needed. A good tool is the sum of its attributes combined, and in that regard, I rate the Akimbo very high. I just feel it was a mistake to take away its ability to support you when leaning back when it is on a chest harness.

    I will be curious to know your thoughts on the Akimbo, Jed. I was using my GoFundMe version today on a large willow reduction. It works great for me but I'm not sure I would like the changes RE made to the tending shackle. When I'm clip into it, I can lean back and it will support my weight. It makes things more stable. With the RE version they changed the tending point to a quick release spring clip and you can no longer do that, it will just unclip from the shoulder harness.

    Good luck, Eric. Having tried many hitch configurations I still prefer a simple four wrap with the cross on the spine side. I suspect that most people that become discouraged with the HH have been using too much hitch.

    Yeah, Vortex runs fine through all the rope grabs that I have but it is a soft rope and can pick easily when new. Not really a problem though. Vortex has a lot of grip potential so you can normally use less wraps or run a looser hitch than you would on a firmer and thinner rope. I am still using some 9mm ArbPro that I got a few years ago. It works well, lasts a long time but is getting tough to find. Both 8mm and 10mm ArmorPrus work well but it is pricey stuff. Surprisingly, I like the 8mm better. Of course the old style Beeline also works. I have not found the HH2 to be as fussy with cords as much as how those cords are tied and adjusted. With so many new cords out now you would be doing yourself a disservice if you didn't play around with some. As you work through different setups don't settle for mediocre performance. The HH2 can work as well as any tool I have tried when dialed in but nothing out there can match its compact, rugged, straight through design.

    Vortex is 12.7 and is my go to rope with the HH2. It makes for a fantastic tree working combo, strong and smooth with a static feel while working but has some ability to stretch in an overload situation.

    LOL! Change can be good or it can suck but in either case, it will happen. Just look at the tools we are now climbing with. The new acronyms really aren't any longer, but hopefully they will paint a more accurate and less confusing picture of what is happening. This may only be the case though for new climbers that don't have to relearn their meaning.

    Those two are plenty regardless of how much you climb. The best of the best. The ZZ looks cool and, aside from some early problems, seems solid. People that use them all seem to be well-satisfied. For myself, I just don't use MRS enough to even bother trying one.

    DMc replied to a thread Time to start climbing. in Climbing Forum
    Welcome to the house, Kevin. I will second everyone else that recommended buying separate pieces instead of a kit. For doing what you mentioned as your primary activity, "As a general contractor in PA who occasionally removes trees for additions or new construction," it would be easy to waste money on things you will not need. Honesty, you will not need much in the way of gear for simple removals, so don't penny-pinch on these items. Get good comfortable spurs. My choice is the DMM Geckos. They're ultra lightweight, have offset shanks and wide thin foot bed that makes them comfortable to use even with heavy hiking boots that have arch support. Get a heavy, thick flipline, not a thin, lightweight lanyard. For simple removals you will not need a fancy harness because you will not be spending hours hanging from a rope or being sideways on a limb tip. You can go sturdy and inexpensive here. Stick with 1/2" double braid, polyester climbing line for climbing and get something different for lowering limbs if that will be needed. Keep it simple and don't go beyond what you feel comfortable with. Good luck.

    Sean, I cut my HH cords to 40" but you might want to go longer than that until you get a new cord dialed in.

    I had pretty good results using 8mm Armor-Prus with the HH. If your interested in experimenting you should try some Arbpro 9mm. That is still my favorite. https://www.gustharts.com/climbing-equipment-c1/friction-cord-slings-c22/friction-cord-per-metre-c23/arbpro-9mm-xs9-1-p108

    DMc replied to a thread This is the Akimbo in Gear Forum
    I run mine with the bottom set 2 holes less friction than the top arm but it will vary. I also do not set the top cam so loose that it is wholly dependent on the spring action to make it work. The Akimbo is so quick and easy to change friction settings, don't waist your time climbing on it if it's not right, even mid climb. One pin hole difference can change things without any great risk in doing so.

    If you look closely at that chart, (assuming I'm reading it right) it shows that the butterfly valve dumps a lot more than the others when it is just beginning to open. Being that it is holding high pressure air, that makes a big difference and gets things going with authority. I really, really want to play around with a coil spring under the valve arm. A trigger would make it way better and its damn good as it is.

    Having the butterfly valve is a huge improved over the ball valve. Not because it is stronger but because it dumps the air chamber faster and with less physical movement. I also agree with OF that launching from a shoulder position is the least consistent. Not a fan of CO2 (as it will change with temperature) for the load force or the use of a red dot sight that limits you to positioning yourself to sight down it. With a 12oz bag and 1.75" zing-it the APTA should reach close to one vertical foot per pound of chamber pressure.

    I'm having a lot of trouble making the math work on this. The plan is to extract a carbon source, using energy to do so, transport it, using energy to do so, and then transport the waste byproduct to land areas and incorporate it, also using energy, but we can still somehow come out carbon negative? Terra preta is a designation of a specific type of soil. It is black and has a high carbon content along with a whole bunch of other stuff. Adding charred by-product to soils of different types has not yet been proven to be across-the-board beneficial nor does it in anyway reduce atmospheric CO2. Not to nicpic but your example of burning a match as being an example of pyrolysis is actually an example of combustion.
