depends on your set up. if your shooting under a 60lb draw weight i suggest a fixed blade.

-Muzzy 3 blade
-slick tricks
-NAP Thunderhead.

If your draw weight is between 60-70 and you want to use mechanicals you can, i still prefer fixed blade most of the time.

The mechanical broadheads i suggest are...

-Nap Spitfires
-rage 2 blade
-grim reapers
