TFOX,

I've stated previously that every bow is different and no one thing that I changed gave me 23 fps. It was accumulative. STS 10 fps, Vapor Trail Strings 10 fps, speed nock would probably be the other 3.

My buddy tried his STS in every position on his Matthews and it made no difference at all.I've test and record results.I haven'texceeded the IBO or modified the equipment in sch a way to tamper with my results.My results are what they are and I'm happy. Not everyone will get the same results with the STS or strings. However, my buddy picked up almost 10 fps going to Vapor Trail strings himself.
