Just my 2 cents. I like the SUM. you can't put it on wrong (unlike gri gri) easy to keep up with, before every right hand new grab after gaining 3-5 feet, I just catch it up. Then it is really easy to rap down with it. Needs the 9.0 to 10 mm rope, not the fat stuff. (sounds like you already have lots of good answers but it is not expensive and have been very happy on many solos.) |
