I was looking over some Cherokee bow specs last night , I'm no exspert but if you have strait grained 1/4 sawn with out any run off & 70 in. & your looking for 55lbs. @26in. , I don't think you would have much of a problem meeting your goal , especially on a bendy handle & good wood like that ,most Cheokee war bows where pulling excess of 70lb granted they where stave type bows following 1 ring .but on paper it looks like you could get what you looking for.
