RE: How much draw weight is too heavy.
I see locals who are obviously overbowed frequently. Overbowed can encompass not only draw weight but also draw length.
On the draw, you should be able to hold the bow straight at the target and smoothly pull it back directly to your anchor point without contorting or struggling in any way.
Personnaly, I feel that the high let-offs get more people to overbow themselves, because thety can still easily hold it back there. I also think that the trend to short A-A bows is leading many to have too long a draw length, because they still want all the "conventional" anchor points like nose to string or kisser and such, but the sever angle make you draw longer to attain those.
I agree that there is a difference between hunting bows and target bows, and I hunt with 65# but shoot indoor rounds at 55#. Sure, I can pull a 70+ pounder back, but it is more than needed. Also, when it gets cold out and you have been on stand for a long time, pulling the bow back become a little more involved and I want minimal movemnet.
