Within your stated parameters, I'd choose a tubbs or strike flatwire spring with the kynshot hydraulic carbine buffer or a good ol H2.

+1. I'm a fan of the Kynshot Hydraulic's....specifically the RB5005 (carbine length) and RB5007 (A5 length).
They make other variants that are stiffer but I don't like them...all documented here:
http://www.c3junkie.com/?page_id=325I have also tried the Cozad and the Omni Robusta and neither work in full auto which is a deal breaker for me.
I have tested so many buffers and boiled it down to the Kynshot hydraulics #1 then just go to an H1 or H2. As mentioned in the other link I posted above, I run everything in full auto with various calibers/configurations and have never had the Kynshots leak but have had the head fall off and each time they have sent me replacements with improvements to correct the failure. So far, the latest versions have not failed me. I would stick with an H1 or H2 if you want no concerns of anything failing.
But for me, I find the difference clearly noticeable and worth it.
I was at the range this past weekend with a friend that is relatively new to guns and got his first AR's and he brought his brother alone that is even more green.
He got a 16" mid and a 7.5" pistol. Both came with H buffers.
We swapped both with Tubb flat springs and they were both amazed at the difference.
Then we swapped both with RB5005 and both noticed the difference in softness / felt recoil. One of them thought we changed to weaker ammo.
I noticed you are in FL also. Where do you shoot?
