I was at the pro shop today and checked my Mathews Rezen 7.0 again today on there cronograph and the speed was 264 for 4 arrows. This was with the ICS Camo Hunter/340, 100gr tip with Fusion vanes. If you ask me that's plenty fast enough to nail down a deer at 20-30 yards and pertty flat shooting to boot. It's been said that once you go over 300 fps the arrow flight can really get finicky. Suppose to be to much power starts to unstablize the arrow flight being there is just to much power for the shaft to handel. Just something i read in one of the major bow magazines.
