My 66" Black Widow LB is great at my 31". My brother has the same bow, only a pound heavier, and he draws 32.5". I've had mine since about 2009 and it has consistently put a smile on my face when I shoot it. My only regret is that it is a hair shy of the 50# for hunting some critters in Alaska!
I also really liked the Toelke Lynx 3 piece, which I think was 66", that I borrowed for several months a few years ago. Sweet, sweet, sweet at my draw. But Dan doesn't make them anymore and you'd have to buy one used.
