Thanks for the feedback, Craig. I did finally find a bow, in fact it just arrived today (58"). Turns out the length isn't an issue for either stack or pinch, it shoots fine at my draw length (even though tillered for 27") and is actually a 1/2" shorter when strung than is my 58" Super Shrew. The grip section on this one is amazingly short (apparently made for a small hand) but like a Hill still lends itself to a firm hold, which I prefer. Nice and quiet, very smooth and throws an arrow surprisingly quick for the poundage (around 48# at my draw).
You're right, Pronghorn's are nice little bows. I like this one.
