RE: too fast for fixed heads?
i shoot about 305 and am using magnus stingers; they impact right where i aim... although i do notice that it takes greater shooting abilities to shoot higher speeds... some say well i can't tune my bow at 70 pounds when in reality they can't shoot that much weight consistanly... nevertheless, what i am saying is, shoot a weight/speed you can handle and everything else will work out fine regardless of the size of your broadhead!!!
