Overall I like the spitfires but I feel you need to be pushing over 60 ft/lbs of Ke to get the most out of them. Of all the mechanical heads I have tested the spittfires are one of the best in terms of quality of construction. Performance wise they are right in the middle of the pack.
I have about 75 LB of KE with the X Force. I would be using the 85 gr. Spitfire.

I have some of the Rocket 3 LT 85 gr. heads, but they advise using 2 rubber bands when shooting over 300 fps. I do not want to use 2 rubber bands, as I don'tthink they don't open that quickly when only using one. The Spitfires have sharper blades too.

Here is an exit hole with my NAP spitfire 100 grainers...

Always pass through on deer ...I'm shooting 65 pounds going about 270 fps out of my Hoyt. I left 2 bears dead in 20-30 yards with these too....Great head!..lots of kills with mine...

Go for it!

Barry,
I think if I were you, I'd ante up and get the 100gr heads, that would get your FOC around 12% guestimating, which should give you a little better arrow flight, and you'll still have plenty of WHACK when it gets there. Actually, you may bring a little extra KE upping your set-up 15gr. Just my thoughts though...

You are using a weak bow now. You REALLY shouldn't be using mechanicals with your setup. You can't complain of penetration issues when you are shooting 50lbs or less and using mechanicals.

I've taken a couple of antelope and a couple of deer with them. They worked well for me. No complaints. They all opened and left a good exit hole.

I tuned for different arrows; now, I would be using the 100 gr. model. ;)
