I did a bunch of bbos years ago and found I preferred no more than 2" of total deflex (from back of arrow pass to most shallow), 1/2" reflex net at the string grooves. I've owned a Super Shrew and built 2 r/d glass bows, one my form another a KennyM. Found about the same in glass. I like the r/d to run the whole limb, like two semi-circles, not concentrated on the outer limb or not flat in the handle. Seems like a real good rule of thumb is to let the wide wood work (inner limb) and use the r/d to stiffen the mid limb (versus stack height or width within reason) and keep the outer limb as narrow and stiff as practical.
