I have read here and at other sites that ipe performs best If you keep em narrow ( 1- 1 1/14") and thicker. I also have an ipe 2x4 - I am cutting it in 5/8 thickness. I saw, last nite, on another site, an ipe/boo bow that was 69" 3/4" wide, that was a D in cross x- like an ELB,. It was a bow that flexed thru the grip. It looked as thick as its width. It was 65# @29. The guy said that w/ a FF string, 500gr. arrow, he hit 191 on the Chono. What I take from this, is that narrow ipe is a good way to go, and likely a good deal of rounding in the belly might serve a guy well-- At least that's what Iam going to try on my next one. (Think I'll forgo the bendy handle, for now) Be sure and wear a dust mask-- the stuff is toxic--and it is culumative -- you are going along fine, no sysmptoms, and than one day your body reaches a theshold and you are suddenly in a world of hurt-- as in under medical care for months. If you get a sliver, get it out, right a way, -- They can really fester if ignored.
