I've been through 6 or 7 sets of Catfish strings, never had a problem with peep rotation.
Archery Shack update: I won’t buy another set. They are okay for the price but the two set have started to fuzz with about 75 shots. I am not totally sure but I think they are a 24 strand build. Should be durable but thicker in diameter. Either way I will be moving on, or I guess back to catfish customs.
