I shoot NAP mechanicals Spitfires with good success from a crossbow. However, by the time I get through practicing, qualifying, and hunting, I go through many broad heads. At the excessive price of the Spitfires, I need to find better value for my dollar. I do follow the rule once you take a deer with a broad head it is too dull to use again. Maybe I am too cautious. I've never been too good at sharpening.

I am considering moving to fixedblade Thunderheads. What downside do you see with this change? It appears that they fly the same though I was expecting a drop off to the left. I have been told that fixed works better on a deer that is quartering.

Flight with Broadheads on a crossbow bolt can be tricky. I am currently building crossbow bolts with extreme FOC built in which will help with better flight, smaller groups, and increased penetration.

I hope to have them on the website soon! I would not think a huge amount of practice is necessary with a crossbow once you are setup and sighted in.

Not necessarily. That's totally dependent upon which mech you're using. I'm not familiar with the Spitfire, but I know I've taken some hard quartering shots with my Grim Reapers and had no problems. It depends on how far the point extends past the closed blades.

Again, I'm not sure about the Spitfires, but Grim Reaper makes some sort of "gizmo" that goes on and keeps the blades closed for practice. I didn't know this until my brother told me about it. Also, the replacement blades aren't too expensive. To be honest, though, I never really practice with them. They fly so much like the FPs that before I go hunting, I just put them on, make sure they are functioning properly, spin them to make sure they are mounted true and put them in the quiver.

If they are impacting the same as your Spitfires, there really is no downside. Just out of curiosity, why were you expecting a drop off to the left?

I use the Thunderheads in my XBow...good flyers...but so are the Spitfires...

I've used Thunderheads exclusively with my 150 lb. crossbow, never had a problem. If it ain't broke...

Spitfires are devistating, i wouldnt change if i were you.

Right on. I've been using them for almost ten years and love them. Just like you said, they are devastating.

For you guys using the Spitfire's, do you always get a full size entry wound?

They produce an excellent entry wound and an exit wound that will rival any broadhead, even the Rage. Just like said before, they are pretty devastating.

This is for sure...the exit wound is devastating...
