[quote=SwampCollie;3438135]Todd is all over this one like white and rice and has it smothered and covered.

Just as an aside though... if you are wondering about spine reactions and what not... field points are cheap... shoot a couple 100s and a couple 125s and see what the difference is... walk them on back to 30 and 40 and even 50 yards.... I think you'll find your 125s will drift.

I've shot 125s for a long time.... but that was on 70# bows.... usually backed down a bit... and on .340 arrows that were boarderline stiff.

I bought a 60# drenalin this spring... and with maxima hunter 250s at 28" (finished) and 125gr heads.... for the first time in my enlightened (meaning since I learned the difference between a turd and wild honey with regards to archery) I had some problems getting my broadheads and field points together.

On a wild hair... I broke out some montec 100gr pre-seasons.... and instantly FPs and BHs came together with dang near no adjustments at all (which was pure luck).... so now I'm back to 100s.... with more Slick Trick Mags on the way... glad the blades from the 125 mags are the same... got plenty of spares already ;-)

In hindsight... I downloaded a demo of AA... or OT2... I forget... plugged all my info in... and 250s with 125s came up a shade weak... went back and amended it to 100s... boom... literally perfect on the spine scale.... might have saved me some headache to start there rather than finish there.[/quote]

I have used both and AA is usually a tad stiffer than OT2 but as we all know,stiffer is better.I have even heard it said that Easton recommends AA for spine selection BUT THAT IS INTERNET HEAR SAY,do not know it for sure.

I did try some old broadheads I had laying around from GKF called dead heads.On the 500's,they impacted several inches right.I never had much luck with those broadheads.The blades were angled and I think the blades just took over.
