Sorry that i did not explain myself in more detail, but I did not have much time to post that question. I am shooting an older model PSE and I am drawing 68lbs. I am using carbon arrows that are pretty heavy. I can't look now because they are out in the garage. I use 100 grain broadheads and I haven't chronographed my bow yet. I am relatively new in archery and I am just learning the finer points. I am not complaining about the rockets, I was just wondering if they were the best on the market.
