No, but arborplex is about as perfect as a rigging line can be. I run 1/2" as my lighter rigging line, and sometimes even run my grcs thing and a pulley on your main spar. Redirects are done natural crotch, and sometimes the main rigging point is too. Working over structure it's very nice to be able to lift, rig, or if it's convenient (it's pretty much always convenient) to be able to redirect the rigging line just by tossing it thru a crotch. It also works great for when you have intermittent rigging needs, since you can call for the rope when you need it, toss it thru a crotch, and you are rigging and not wasting time or effort. It does kinda suck on the winch tho, it goes square and it's so slick that it slips a bit. Which is why it works so well natural crotch.
