I have, or have had, both a Dave Beeler 56" Hybrid, and a 56" Big Jim ThunderChild. You couldn't go wrong with either. I'm on the list for a 2pc ThunderChild and will probably get it in a 54" length as I draw 26".
You won't find either of these come-up used much, as the ThunderChild is a fairly new model and I expect folks will hold on to them, they are awesome bows . Dave Beeler just started offering his again after a lay-off and I don't know what his wait is.
Shrews have a long wait, but have been around long enough that getting hold of one used is easier. Watch the classifieds for one of them.
