I have similar problems because I have such a short draw length (26") I just switched to 250 CX Maximas and love them so far but Roskoe is correct better to be stiff thanweak I am shooting my ideal spine of 0.415" now with the Maximas but have been overspined for a few months with Vapor 5000 arrows at 0.300" However they still flew good. I think you will be fine with your draw weight I am shooting 70-80# bow and the 250 's I have now are good to go for my range.
