RE: If you could choose...
If you are already shooting ACCs, personally I would stick with them. I thought about the Superslims, but why? Don't really like the HIT thing. I'd much rather put another G-nock in a unibushing that was hit than a whole new arrow when the X nock is smacked. I haven't heard that many people being overly impressed with the FMJ, I think Easton has to hype their newest offering.
Boy, Rack is into light arrows, huh? I really like my CT Cheetahs. I only have the hunter grade, and they shoot just as well as my ACCs. If I put out somewhere close to $100 for new arrows this year, I think it would be for CT Panthers.
