I guess after reading the others' posts on this thread, I have to revise my earlier opinion. Thinking back on my intro to trad shooting, I believe the 45# was a good way to start, and I remember the problems I had even at that weight with short drawing, etc.
While I agree with Broker that you very shortly will be wanting to shoot heavier poundage (I know I did), the 45# bow will just give you an excuse to get another bow. And we all know you can never have too many bows. Just ask John Nail!
