I have never felt like the porty has a 'limit'...if the rope holds the porty certainly will.
Usually one wrap is all that's necessary for smaller loads, especially if you're natural crotch rigging. It would be interesting to see the corrosion on your porty. Post a picture, if you can.
In terms of pulling the porty is very good for capturing your progress and locking off the load, but doesn't play any part in the actual pulling itself.
Makes it so you don't have a knot to cut off the end of your rope though after the pull![]()

Oh yeah, that's a good use as well. Anchor the rope to the porty and then just pull the porty instead of the rope.
