Yes, I have used quickspins. I put as much offset on them as I did the blazers. The arrows flew the same. How much offset do you really think you can get with a 2" vane, assuming he is using the 2" quickspins? Did you try them with an offset? Did you try them with as much offset as you could get? If you tried them with an offset and not a helical, how did they fly? I did not suggest putting a helical on them maybe that is where you are confused.
