I shot spitfires this year at 68 pounds and had mixed emotions about them. They leave killer blod trails and fly very true BUT I was a little off on shot placement on a deer and hit its should and the arrow hit and fell out. Not the best on penetration. Go with a fixed. One thing I do know is the guys on this forum won't steer you wrong they know there stuff.

well thanks alot guys the info should help me out alot.

Alot of wise advise here. I agree, stay away from mechanicals with
your set up.
