I prefer the brass inserts due to broadhead flexibility. If I want to shoot a lower cutting diameter fixed head for elk I can do so then spin those off and spin on the spitfire max for whitetails and knock honkin big holes in 'em. Thats for my compound setup, for my recurve it all big heads and standard inserts. Funny part is there is only 10 grains different in total front weight between the 2 setups. I just wasnt smart enough to build them to be interchangeable. LOL
