I have tried the 125gr 3 blade Muzzy and can not get them to fly that well at longer yards. I have shot the Rocket ultamit steel 125gr. 3blade and they fly great but do not like the head. I want a cut on impact head with 3 or 4 thick strong blades that will fly well. The hellfire I think has thicker blades than most others. They are expensive and wanted to know others opinions before I spend the money to try them. I am shooting PSE cabons at around 275 fps. Thanks Dave
