stringstretcher,
The bows are rated 52-55#@28.
Although none of these bows are center, I've found that 10# additional spine will probably work for me. My draw is generally 28.5 to 29 depending on the bow.
Given the natural taper, my draw, and heavy front loading, I would assume that 65#'s should work fine. I normally leave cane shafts 33".
Let me know what you think?
