I have a long draw at 31.5". I'm not sure how the newer black Widow bows draw, but the older ones had limbs that open up very smoothly and did not put a lot of stress on the fadeout portion of the limb.
I like the way a short Widow draws even with my draw length.
I designed the limbs for my bows to open up like the Widows. I find that even when I made a 60" bow for someone that I can shoot it well.
At any rate, take a look at a bow's unstrung limb shape. If the limb is mostly straight with a gradual taper and a narrow recurved tip approaching 90 deg, it will draw smooth all the way.
Limbs that are shaped like a hook and have a lot of "backset" are more specificly suited for a certain draw length and are going to loose the sweet spot after you get past the 28" draw.
Find yourself a Black Widow 60" and shoot it....I bet you will like it......Just my opinion...
