Great line for Mechanicals I have used it with the Zig Zag and Rope Runner Pro and it is the best line I've used with both and I've tried a lot of ropes. Drenaline is the only line I climb on with mechanicals. There are a couple things I don't like however and is why I can't give it 5 stars. It milks a lot I got about 2 ft out of a 200' hank when new and the more I use it the more it milks. After a month of use I got another foot or so. The other thing it is not the best with a friction hitch it seems to creep more than other lines. I have used a 8mm Beeline and 8mm RIT tieing a VT and distel none of the combinations seem to hold on drenaline as well as they do on something like Blue Moon or Hyperclimb or any standard 24 strand double braid. If you are looking for a line to use with mechanicals this is it but if you are looking for a line for a friction hitch there are better choices.
