I see you are from Arizona USA, but find myself asking if you now reside in the UK? Both these tuners you mentioned are based here in the UK, and you usually get their contact details from a owner who has already had work done by them. I'm concerned that if you are based in the USA there maybe issues with sending the rifles action to the UK for tuning, and the same issues returning it across the pond, and I dread to think what shipping costs both way would cost.
I have not had work done Nick Gibney, but my .22 TX200HC Mk3 has recently returned from a stage 3 tune with titanium piston by Paul Short. It is a better rifle for the work done too. No twang, little recoil, so much so when shooting it with a fairly thick jacket on, I felt no recoil at all. Accuracy is on par with its pre-tune status, but is is showing much more tolerance to other brands of pellets, where it would only shoot AADF & AAD Hunters previously. It is harder to cock than the standard rifle.
Working on the assumption that you are located in the USA there are two other options I can suggest. Firstly, TBT drop in tuning kit. They do a kit which contains a new spring (Maxi kit) for those customers living in countries that are not restricted to the UK's 12fpe limit. There are many youtube videos on how to strip your rifle and install these kits. I had one in my 177 TX200, to good effect I might add.
The second option would be to fit a 22mm Tony Leach conversion. As far as I'm concerned this is the bees knees. Simple kit to install, super smooth easy cocking, no twang, just a simple reassuring thwack when fired, no recoil that I can feel, no muzzle flip and very accurate.
@cactusjack if you would like to confirm where you reside, USA or UK, I will contact both Paul Short and Tony Leach and ask for their permission to pass on their contact details.
