In reply to UKC Articles:
personally I don't like splitting the belay ropes between the fingers like that for a few reasons:
- I feel that a fall could lead to some nasty friction burns between the fingers and then could possibly result in the belayer dropping the leader due to pain.
- I also feel that with many belay plates /rope combinations it’s likely the grip of two fingers may not be enough to hold the leader.
- Finally as can be seen in the video there is not always a firm grip on both brake lines whilst taking in (it equates to taking in without doing a hand swap over on a single line), which in some cases could result in a ground fall.
Personally I find for paying out on one of the ropes it is not necessary to split the ropes at all as the guide hand just pulls on the appropriate rope and the brake hand lifts them both and then slides back down.
For taking in on one of the ropes the guide hand can just pull the slack from the brake side of the belay plate forming a loop (whilst keeping the leader on brake by holding both ropes below this point in the brake hand) and then a hand swap over can be done in a similar way to taking in when belaying using a single line (instead of half ropes) but holding both ropes to get rid of the loop on the rope which was just taken in on. (the guide hand grabs both ropes just below the belay plate and the brake hand then lets go of the brake and lets the loop of rope drop before holding both ropes again, at which point the guide hand can let go of the brake lines and go back to guiding the ropes above the belay plate.)
Ofcourse it's not possible to safely take in on one rope and pay out on the other and as giving rope is normally more important than taking in when the leader is moving quickly, in this case I would very often not take in at all and just pay out on the rope with less rope out in the system until both ropes are equal. If the leader stops then the above methods can be used to get both ropes in to a more balanced state.
