JC, are you loading up the front end to get those monsters to fly out of your 70lb recurves? I shoot 31" BOP 75/95 Goldtips, both XT black (.34) and XT traditionals (.30). My 73# Dale Dye likes the black XT's best with 335 grains up front, my 76# Dye likes the XT trad with 310 grains up, and my 80# Ancient Spirits likes the XT Trad best with 275 grains up. I'm looking for something heavier for that Ancient Spirits as I'm only at 643gr and 8gr/lb with this set up, and this CarbonTech might just be the answer.
