spitfire 125 broadheads
 

I shoot the Fred Bear TRX 32 at 60 lbs., the aarows i use are Easton Camo Hunter XX75 2117's. do you think that I would get enough KE for the spitfires to open? Thanks for any help.

I would consider the 100's v 125's. The 2117's are a little on the heavy side, so you may have a problem with the heads opening. I know they have a new spitfire cut on contact head that may help on the entrance of the broadhead.

GO TEAM 10!!!!! THE BIG TEN!!!!!!;)

Go to the NAP website at www.newarchery.com and enter the faq section. The answer to your question lies in the kinetic energy produced by your arrow at a particular range. NAP recomends 50 foot pounds as a minimum for opening the spitfire and this is a function of arrow speed and total arrow weight so you are probably allright with the 2117s and a 125 gr head as long as your speed is not compromised by something. Check out the sight and do the math for yourself.
