I have seen these on a few arrows and bought some to try out. It looks like they will go around my carbon shafts about 1-1/2 times. Will the extra few grains on one side of the shaft affect arrow flight that much or should I not worry about it?

Also, I remember a post on here where someone said they had a chemical to strip off the crests. What was that stuff and does it hurt the carbon shafts?

Thx
