I had Vapor Trail strings put on today with the new cam and everything is working great. I don't have a chrono, but I for sure didn't lose any speed with the new strings. Everything was shooting high so I had to readjust my sight. I might have picked up some speed. So far no peep rotation. Again, Rick at Dickson Sportsman does an excellent job and was able to work me in with the mob of incoming turkey hunters.
