Of all the materials for bow strings, I think UotraCam is the most stable for peep sight rotation. Especially in cold weather. The only problem with it is, it is a little slower too.pblawler said:
pblawler is right. If you are going to shoot in these types of weather condidtions I would have the string setup for it. In cold weather, I would leave the bow in the vehicle or someplace where it would be at the hunting temperature.
Then, I would press the bow and move one of the strands from one side to the other of the peep. It that didn't stop the rotation, I would move another. Eventually, the rotation stops. Now you may have to move several more, equal numbered strands from one side of the peep to the other until the peep properly orientated.
However, generally, a well made string doesn't have theses problems.
