Without a doubt my favorite broadhead is the Muzzy 100 grain 3 blade.

There are a tremendous amount of great quality heads on the market today. Most you'll never have a problem with but....the key to success is sharp blades. Use the one shot rule: One shot and they are done as a hunting head unless the blades are either sharpened or replaced, period....don't practice with them and use them unless the blades are sharpened or replaced.
