Magnus II, Ace. I'm still using my Magnus broadheads. They were 100gr plus the adapter which puts them around 145. I won some Ace broadheads that are a little heavier. They both sharpen fairly easy, fly just about the same, kill deer when put through the lungs (like just about anything you could drive through a pair of lungs) give me pass thoughs with low 40# bows, seem quiet enough, look mean enough, don't cost too much, don't really make me look too hard for something else..although I have played with some 3 blades and notice some have noticable different impact points . So Magnus and Ace would work just fine. So would alot of other heads. Settle on one and make sure they all fly true on each shaft you put one on.
