There are alot of good head out there, what it really boild down to is personal preference, I have shot NAP Spitfire in the past, and the performed flawlessley...never had one failure...but in doing some research I have discovered some mechanicals as well as fixed that do one heck of a job also...
For mechanicals this year I am going to try InnerlocsEXP Series 100gr....and for Fixed I will be going with the Innerlocs 100's & 125's Carbon Tuner BH's... I have put these to the test on targets...
I will let you know in awhile what they do on flesh...
