I've just been browsing old posts on half ropes. I just bought a new half rope to use in conjunction with a half rope that I've been using as a haul/rappell line for about a year (maybe a dozen times tops).
All of a sudden I'm worried! I had intended to use this system for alpine climbing this summer, in order to save weight--twice in the past I've been on the Diamond, climbing with partners' half ropes. They told me that usually you just clip both into the same biner, no problem, or for wandering pitches, you can alternate clip--they seemed to suggest that that was the exception.
So I've been intending to use these ropes not only for lower-angle wanderfests, but also for steep, straight, at my limit routes, e.g. Pervertical or D7--routes where I certainly might fall. But then I dredge up these old posts, where multiple people have said clipping both into the same piece of pro is very very bad! None of the company websites I checked mentioned this, nor did the fellow at Neptunes when I asked him for all the dirt. I can't see how anyone would ever climb near their limit on half ropes if this is true-- you are faced w/: 1) taking the fall on both ropes, clipped to the same pro or 2) taking a fall on a single 8.5 (how bad is that, anyone--especially if it's say a 30-50 footer?) or 3) clipping both to the same pro but with different biners (too much extra weight, and hard to do at your limit).
Can anyone explain exactly why it is so bad to clip both to the same piece (is it because of the fall factor, the ropes rubbing against each other, or what)? And exactly how bad is it? And just how bad is option #2 above?? Would there be any difference between clipping say the bomber #3 friend on Pervertical verses the perfect #4 stopper on the thin cracks of D7? I'm really worried that I've made a useless purchase here! I need reassurrance or resolution!
