I think it's great that you're upgrading, man. You don't have to sell me on what the ATI's can do "anymore". LOL! I already bought the other fixture.
It's awesome!
I talked to ATI North America this morning on the new ATI Straton. They couldn't tell me when they will release here, but I'm watching closely to see how they compare to the ATI T5 fixtures. I'm hoping BRStv does a lab-up on them.
Let me know how you like the G5's after a bit of time goes by. I'm still on the fence with the whole "LED thing" after many failed attempts in the past.
