I bought a Bear Whitetail back in '75 and killed a bunch of deer with it...I had it set at 55 pounds and was shooting 32 inch 2117s with 125 Satellite heads...I got pass throughs out to 25 yards, which was as far as I felt comfortable shooting anyway...

One thing you might try...Set your top pin at 15 yards and the bottom at 25, for 20 hold between...
Seems that most of my shots in the woods come from 12-17 yards or so, so you end up using mainly the top pin...

Down here a 25 yard shot in the woods in Sep/Oct is a long shot anyway, the leaves are still on the trees...
