I like biner brakes, too, but I think I may be about the only person left who still carries ovals.
Closest rappel f/u: Sporty and I were beating a hasty retreat from the E. Direct on the N. Face of Edith Cavell amidst a real artillery barrage of rock fall. One of the scaredest I've been, and he still says the same, even after three tours in Iraq in the seals and catching an AK round in the chest (gotta love ceramic armor). High stress situation, about 600' up the face, and as he leans back to rap I look down and realize only one rope is through his ATC. Fortunately I grabbed him before he went to the glacier and took the ropes with him.
