It depends on the bow and cams. Experience would tell me you're in the ballpark at about 65#, but being as you already have the CX 250 I'd give them a try and see how they tune. If they tune OK then you're good. If not then you either have to get a stiffer spine or drop the draw weight down till they fly OK. Me? I'd drop the weight. I'm not into heavy draw weights or spending money for arrows. Those limb bolts are your friend.
