After seeing my buddy's double ropes in action a couple of times (a bail-off of Moby Grape in a thunderstorm and super easy protection for the second on the pitch 2 Book o' Solemnity traverse) I've decided to get myself a pair for this season.
I can get a good deal on Beal and Mammut ropes and have been looking at the Beal Cobra 8.6 and the Mammut Genesis 8.5. The intended use of these ropes would be for both multi-pitch trad and for ice climbing in the winter.
As the price is just about equal between the two, I've been leaning toward the Beal as it has a lower impact force (5.1 kN vs 6.3 kN) and higher fall rating (16 vs 11). I'd appreciate any input you guys have from your own personal experience.
