Tom,
Like Eric said,,"jump on in the water's fine". It's the most addictive defined discipline I've come across. The rifles run from here to there and back again. I have underhamers that go from 14# to over 40#, both flint and percussion. I have one of Ron Borron's available in flint with a 54" barrel and full stock in .40 caliber. There's also 4 original chunk guns on the wall, all in percussion. You name it and someone's tried it. Full stocks, half stocks and no stocks. Percussion, mule ears, percussion, flint and underhammer. Come on down to the York with Eric and you will really get an education.
P.S.; I can send you some pictures but don't know how to post them.
Mark
