Tuner advice: Brenspeed, Bamachips, or suggestion?

For a while, I had been considering a local tuner (great guy, not a ton of experience w/S197s) for a custom dyno tune. Now, I'm leaning toward one of the more experienced tuners out there (Brenspeed, Bamachips, etc). My setup is nothing out of the ordinary (JLT CAI, JBA LTs, JBA shorty H, JBA axel-back) so I figured that these guys have probably already tuned many cars with this exact profile. So, I'm looking for recommendations on who I should work with. Also, I see that the Xcal-3 is now out. Should I stick with what's been tried and proved (the Xcal 2) or go with the latest?
