I agree with the bowmaker tuning information.I would also say,make sure you know your real draw length,decide if you want to shoot wood,aluminum or carbon shafts,then ask the Black Widow guys here what spine shafts to get for a given weight range broadhead.Then follow the tuning method at bowmaker.net.
You can get any weight broadhead to shoot as long as you tune the setup properly.You just have to remember that increasing point weight makes the shaft react as if it were weaker spined so you either have to shorten the shaft,change side plate thickness or go to a stiffer shaft to compensate for it.Good luck with it.
