I still am a firm believer in Muzzy broadheads but made a switch a few years ago to Rocket Hammerheads. The 4 bladers has some penetration issues but the 3 bladers have worked phenomenal this year. I shot my 10th and 11th doe yesterday morning and damn near severed the leg just below where it attaches at the shoulderblade on the one. Knocked through the opposite ribs before stopping, she went nowhere.
Main thing is having faith in your equipment, each and every broadhead that has been mentioned will do the job if it's put through the boiler room. Get your bow tuned up right and try a few different heads, I know that's what I had to do. Good luck in your search.
