Frank,

Have you played around at all with different spines and arrow weights to see what the MM likes. For instance on my FX when I went to the 7595, from the 5575's I only lost 1ft/sec for every 7.5 grains unless I went to a 125 grain head but even there it was only 1ft/sec for every 5.5. That bow seemed to like a little more arrow weight and a heavier spine.
