Over the years I've noticed you are the go to guy for archery advice. I'm considering putting a new set of vaportrail string and cables on my new bowtech rpm360. (I got them for a good price) The octane strings that I'm removing have speed nocks on them and the vaportrail strings do not. So here's a couple questions. #1 am I making a mistake by doing this? #2 how much speed if any will I lose? #3 do I need to just leave the factory strings on it? #4 do I need the speed nocks?
