I have a 1993 I think? PSE Lightning Flight. The sticker says 60-70# 29" draw length. I was wondering if anyone knew what the draw length range is on this bow? I know there are a few other slots on the energy wheels so I know you can change it. I am hoping to give this bow to my father in law as a starter bow. He has a much shorter draw length than I do though. Also Is there a way I can tell by looking at my bow for myself? Is there a rule like one slot per inch or something? I also think the let off is like 60% Also the wheels are aluminum not plastic like the newer low end bows if that makes a difference.
