Joe -
I have two Thunderchilds ("Thunderchildren?") - they are both 56" AMO, and are #52 @ 28" and #55 @ 28" respectively.
I have a 28" draw, and do not experience any finger-pinch with them at all. The draw is very smooth and linear and when you find the proper brace height (I like mine braced just barely over 8") they are very quiet.
The first time I shot a Thunderchild, I wasn't sure how I would like the grip, as it is a larger and more hand-filling than my other bows. But now I really, really like it. I think that the larger grip allows for a really stable foundation on such a short bow, if that makes sense.
While I own several other bows, I keep finding myself reaching for the Thunderchild - it's combination of compact size and performance is a joy to carry and shoot in the woods. And a 56" bow that takes down in two pieces is great for strapping on to the side of a pack for extended backcountry trips.
Craftsmanship, as many have stated before, is absolutely top-notch.
Two options I would highly recommend if you are considering ordering one - get the beavertail grip, and splurge for the take-down option if you can. Jim's take-down sleeve design is as simple and solid as it gets - no hinges, pins, etc. In fact, you would never even know its a takedown bow when it is put together and strung.
