Night Wing,
I'm having tech problems with photo bucket right now so i cannot post a good example, but i have a 60" r/d long bow that will draw to 32" with a better string angle than a lot of 66" bows out there.
the string angle is determined by where the "Working limb" is located. most D shape and mild R/D long bow limbs load more evenly along the full length of the limb. With out any reflex to the tip, it requires more length to get a better string angle.
With recurve limbs, and hybrid bows alike, the working limb can be manipulated through the use of different taper rates in the core, and shifting tip and butt wedges to bend further out on the limb creating a lot milder string angle.
Depending on the design, and the geometry used. You can take an identical 60" bow and make it draw so it stacks up at 26" or 32".
