The last BBH bow I made was 1 1/4" wide, 64" ntn, glued in 3" of reflex before tillering and is an absolute rocket launcher with about 1" of reflex after unstringing.
I made it from a paddle looking hickory bow I made many years ago that was an awful bow, my third or fourth if I remember correctly. I flattened it, narrowed it, backed it and completely reshaped it, even had a slightly rounded belly.
I was impressed with this bow and would make another if I didn't have so much osage.
