The best I can say is, go to your local pro shop and shoot all the different bows they have. And buy the one that you shoot the best, that feel good to shoot and that's quite.
#2. If you buy a bow that's adjustable from 60-70lbs, then you can increase the draw weight as you get going. But I like to increase the poundage and then have it checked at the shop to see what it actaully is.
Well this is just my .02. Hope it helps though.
