For some reason, my other post did not show up. I went to edit it, and most of what I typed was there. Then clicked OK, and it came up blank anyway![:@]
ACCs should be OK with a prong rest with either straight offset, or mild helical. If you want to use hard helical and a prong rest, I would use feathers.
I personally tried out a Whisker Biscuit rest, and have been pleased with the accuracy and arrow security. It will be my hunting rest until I find something better.
I have had a bad experience with Blackhawk Vapor ACAs myself. I only got a half dozen, but 2 of them would not shoot with the group even with field points at 30 yds. The others seemed to break down and lose accuracy faster than other carbons I have tried. I even ruined one of them just trying to take fletching off to refletch. A sliver of carbon lifted up, and peeled all the way back to the back of the shaft. Didn' t trust it after that. I have refletched a few carbons over the years, and that is the only time something like that has happened.
I can get my ACCs for a reasonable price. Otherwise, I would probably shoot Beman ICS Hunters, or Easton Aluminums. JMHO
