I wondered what grain spitfires to use in ten point turbo 2? Also do I need the crossbow ones or any will work? Thanks

I use 125gr NAP Spitfires in my Titan Extreme. They fly great and work well.

Any will work. After trying a few broadheads for consistent bolt flight and performance killing deer and feral hogs, I settled in on 125 gr. Montec 3-blade broadheads. My cross bow is a Parker Tornado. I tried out 100 gr. but found no appreciable advantages, so I use the 125's for a bit more down range punch.
