Comparing Vortex and Imori specs...
Imori is 12mm vs Vortex 12.7mm.
Imori is a little less rope weight.
Both are poly cover, nylon core
Elongation values are apples and oranges, Vortex = 1.4% at @ 540 pounds, Imori = 1.6% @ 650 pounds.
If Vortex has the same hand feel as Velocity (scaled up of course to 12.7mm diameter) then Imori is probably going to win with its more textured surface. But since it's 12mm it might all balance out anyway.
Looks like these ropes are really close.
Has anyone climbed both with the wrench to compare?
