Thanks for the responses. I wasn't surprised by the ACCs, since I've been shooting well with them before, and they aren't drastically overspined. The Cheetahs were a surprise though. I had been shooting them with 125 gr. points to "soften them up", and on a whim tried 100 gr. points, since those are the only Muzzys with practice blades that I currently have. Still needed to tweak the rest a little as the BHs were hitting just a little high, but flight and accuracy were all I could ask for. Grouping was good even with the factory straight offset fletch.
