Backing - ash , white oak, maple all will work well. You must get a board with flawless straight grain for backing heavy bows. Do not ignore the last point I made it's way more important than the wood choice!

Backing might be the problem: seen a wellmade lightweight ipé bow break through the backing. which was thick enough perfect grain elm. With ipé it should be boo or hickory. Jmo.
Ash backed, maple backed Jatoba, long enough, wide enough should work for a 70-80#@30-32"

I find elm is not great at backing anything. It's seems prone to lifting splinters.
I disagree regarding jatoba. It does make good narrow profile ELBs up to about 50#, but I wouldn't go past there. It's prone to chrysalling, and not the best choice for a warbow. As mentioned, ipe is a much better choice.
Ash, maple, hickory or bamboo... all good backing material (with appropriate grain of course).
You can splice the handle on a laminated warbow, and I've done it up to 100#. I made a hickory backed, bamboo core, with a spliced osage belly... 100#@32". Not a good first choice, however. Also, you have to tiller the handle stiff as a result of splicing.
The best laminated warbows I've made (and continue to make) are maple backed yew. 78" NTN, 1.5" wide, 1.25" deep. It's an amazing combination, and dare I say it, better than a self yew stave.
Thesquirrelslinger:
I thought white oak was ridiculously good in tension???
adb:
It is.
AH:
I would have gone with white oak, but I have had really mixed luck with the white oak I've gotten from this store. Some of it was absolutely awesome, and some of it broke right away, even when the board had absolutely straight grain.
I might order the ipe online then. I hear that it's real oily though, what type of glue would be the best for the job? I can't get my hands on urac-185 anymore, and I don't want to pay a whole lot for glue.
adb:
I've used nothing but TB3 on ipe, with zero glue line failures.
