TLF, I too had to go the way of the crossbow to stay in the woods for archery. As we age and the injuries catch up with us sometimes we have to learn new tricks.
I have no knowledge of Barnett bows. You'll do your homework and pick something you like. Even with my bad neck/shoulders I can pull my 200lb crossbow using the string helper very easy if that helps you on the poundage question. Happy Shopping!
