Sorry, I posted a response earlier today, but the house wasn't working from work for some reason. My post went something like...
BEST LOOKING FLY SPLICE EVER!!! I could never "condone" this splice because it is done NOT in accordance with the manufacturers directions. But the factory splice for this just looks UGLY. Your splice, on the other hand, looks quite elegant! No big clumpy bump sticking out, no need for shrink wrap, and smooth overall transition from splice to rope.
I once did a splice in a 10.5mm Mammut kernmantle, dynamic rock climbing rope using directions from a double braid splice. When it came time to burying the cover INTO the core, I just laid the two next to eachother and stitched them together. I cut it off and still have it. I would climb on it in a heartbeat after knowing what I had to go through to put it together. There is no way that things is coming apart. But I didn't want my friends climbing on things that weren't accepted, so I cut it off. I still have it.
It might be worth making a properly sized eye-eye sling and breaking it to see what happens. I think we might be pleasantly surprised! I'm sure Ne_Tree would be glad to bust it for us, right?
Anyone have some newish Fly they can send me? I don't think I have any left now that tachyon is available.
