I don't understand how you even break a bow. Of any type. It's the one problem I've never had before. I suck at everything that's considered easy around here, but all my bows draw past 30" no problem. Even wood bows. Even oak bows. And I never have any set. It's the same thing with flexibility. Most Americans can't touch their toes without bending their knees forward. I can put my ankles together with my legs actually bending inward, and put my hands flat on the floor. Some people are just living in an alternate reality where range of motion is severely reduced.
I agree with you though, you can make a fine bow with a short draw. Making it thicker than usual (like an English longbow) and a good deal of reflex seems to help improve cast on the bows you don't want to draw far.
On the other hand, making bows very wide and thin is a good way to increase draw. More draw = more potential energy storage, but if you're not using straight grained and mostly knot-free wood with most non-conifers, you're probably going to get a break.
I eventually gave up on trying to find good bow wood and just starting splicing short pieces together, and gluing them to handles. Making bows this way is funner, to be honest. Never understood the appeal of character staves, when they're more prone to break and you can build a bow out 12" slivers of perfect wood. Primitives did it all around the world -- see the Tuktut Novait bow, Sheepeater Indian horn bows, Eskimo caribou antler bows, etc.
