Kegan, I've made plenty of pyramid and elb style Ipe selfbows over the years, and they perform as good as any bow cut from a board. Just make sure to keep the outer limbs slender since this wood is much heavier than the native woods..
As far as tension strength goes look at the lpe backed laminated bow I have posted..it's on page 2 now I think. The back of that bow takes a good load..
