49lbs will be close. I shoot the 125 grain snuffers and I've gotten allot of other Trad shooters around me shooting them also. My brother pulls about 52lbs or so and he gets 60% to 70% pass throughs with his longbow. One thing about a 3 blade COC broad head is that there point is sharper then any 2 blade out there. Spinning my snuffers on my finger with just the weight of the arrow will bury a hole. All in all I think you will be alright using them Naps. How heavy are your arrows? That could be a deciding factor as well.
