Mobow, thanks for the additional info.

Based on your numbers, and running compairisons to your setup in AA (Archers Advantage), it *seems* like there is about a minimum of 0.3 to 0.5% increase in FOC on the actual Maxima Hunter arrows over what AA is calculating for FOC.

I did some comparisons with the current set of GT's that I have, and AA nailed the calculated weight, and FOC on the nose. Now, the difference in FOC in AA vs. your numbers could come from anywhere, component variation in your setup, invalid weight values for components I setup in AA, etc. However, bare minimum it looks like i can hit 13ish % FOC with blazers and 125g heads, and push up to 15% FOC by going to feathers. With that in mind, I'll pick up 1/2 a dozen shafts this week and start setting them up to see what kind of numbers I can get.

So, to hijack my own thread, anyone know where can I pickup some Gateway Raysr Feathers? I havnt seen them on Cabelas anywhere, havent checked Bass Pro yet though...
