50/60/70/80 or 100, the weight doen't really madder. I have discover that---if your arrow gets to it target at around 230fps they don't jump the string...
Your max draw weight can be determined by. Putting your pin on the target and drawing back the string straight to your cheek without ever taking you pin off the target....
When I started bowhunting 25yrs ago, for practice, I would draw on every deer that came by, even when they looking at me, and let it back down without spooking them.
