I know I probably sound like a broken record, but if one would mimic their holds on the tillering tree (rope and pulley system), there would be no question. Bows such as these can be tillered by the same methods, using the same gauges and goals as limbs with identical profiles. It takes the mystery and guesswork out of relative limb balance, without trying to make the limbs match in appearance. Besides, do they always inherently match in their behavior because they look alike? Or what if there's a disparity between them that can't be altered?
I have a couple of bows started that look similar to this one that I plan to use to demonstrate what I'm talking about once I get caught up a little here.
