You may be very right. It will be interesting to see at what weight horn and sinew passes wood in performance.

As i think about your point more, I think my first goal should be matching the fd curve of the bow I am imitating. Then the bows will differ in how the materials ability.

But, Joe Gibbs shot a swiss yew and a tatar hornbow. Both 180lb. They shot around the same fps with a 63.3g (976.7 grains) arrow, though the horn bow had been strung for a long time..?

String a longbow for a week and see what fps it gives you! Bear in mind that hornbows were never really designed for extra heavy arrows (apart from a few designs like the Manchu etc). Longbows however due to their heavy/slow moving limbs are.
Sleek - I like your style but you are trying to match an oranges performance with an apples. No wood will make a Turkish shaped bow that is comparable. Horn/wood/sinew can store more energy per mass than any wood.It is impossible as the materials are just too different. You could make a bow that is 'similar' but not the same. Look at big a steel bridge then try to make the same bridge out of stone.

Mike, I appreciate your opinion. I cant say about energy per mass. I dont plan on calculating that. I am only going off of draw length, weight, and ntn length along with braced and drawn profiles. I dont know if wood can match horn and sinew when compared to mass and energy storage. Seems a stretch for certain.
However, I do intened to either do it, or prove it cant be done. As far as Kenetic energy to tje arrow goes, I did come very close to your 48" horn bow with an osage, though it did use sinew. But that does show horn isnt needed.
