Let me be the first one here at HC to welcome you aboard! I'm not exactly sure as to what advise that I could give you-as a matter of fact, I think that I could learn a few things from you.

I've never shot either a Pope and Youg or a Boone-Crocket buck. I am reasonably accurate out to 25 yards on most days but have never won any archery competitions.
There are some other folks on this board that sound like they shoot really well and compete (are ya out here T.Sadler?) and could probably provide better insight than I.
I think that if you are shooting that well with a Whisker Biscuit in competition, a drop away may actually improve your shooting scores from things that I have both heard and read. For hunting applications, I seem to see folks pretty equally divided on the WB for hunting. If it's bagging you P&Y deer, personally, I don't think that I would be changing a thing on my set-up but that's just me. Good luck to you and again, welcome!
