These are the Carbon Revolution Speed Pro Max SS 6.5 grain per inch. My bow went from 272 to 302 by just switching to these arrows. The 5.5 are a little lite and very brittle. So far....no problems with the 6.5 grain. Check out the 5 inch mellon test at 40 yards. (barking in the background is my fans club)....lol!
