like rich said on the twist, get it bending a few more inches and file in some nocks and get it on a snug string, then when you get it bending about 6" or so, brace it to 3" or 4", I think with maple, imo a mush better choice than r.o., you may be a little wide at the fades for the #'s you want at the draw, if it starts getting real thin start removeing equal scrapes from the sides of the bow, I still tiller with a lock back knife like you, good luck and welcome aboard
