1st post here. Been reading for a while. The arrow selection guides are pretty self explanatory but I'm not sure about some ?'s about my bow. Bowtech Diamond Rapture. 60#. The arrows I was sold when I bought it are 29 1/2 total length from nock to point of 100gr. field tips. I've been trying to get it dialed in but have changed a couple things so I am starting again. Just put a fall away rest on (Trophy Taker). The Hostage just seemed to interfere w/ arrow flight too much. I was hitting consistent 4" groups from 30 yds til I started messing with it. The arrows seem to fishtail or corksrew as they fly to target. I am wondering if they are wrong size. They are "RedHead 4560 Carbon Fury" . I figured I would destory several being a newbie so I wasn't too choosy for this 1st set. Anyways, like I said I can do the calculator stuff but 2 questions. Does this bow have "High Energy", "round wheel" or "modifed" cams? The top wheel is round the bottom looks like a regular "cam" shape. Also, "Fast Flight" or "Dacron" string?

Thanks in advance.
