Ummm......where to begin......I wouldn't have bought a bow w/out shooting it first, but that's a story for another day.

First, High Country bows are just horses to pull back anyway, let alone in the 70-80# class......Is it backed all the way down? You should be able to get it down to around 68 or 9 #'s.....

You've had some shoulder surgery, so you may want to rethink higher poundage. 50-60 may be best for you, but I don't know the extent of the injury.

First thing's first...get those brass pins off and find a set of inexpensive fibre optic sights....Cobra makes one that's only around 20 bucks....

A finger tab will certainly save on pain in your fingers, get one, they are cheap as well...bout 8 bucks.
