Is this the correct way to power on Turbo 2x2... anyone with experience?
If the procedure below is not followed the Turbo with not operate.
Mount flash to camera.
Connect Turbo long CZ/short CCZ flash cable between 580EX II and Turbo 2x2, Turbo SC or Turbo C.
Turn on camera and flash.
Turn on the Turbo last.
Is there any reason why you do not wish to follow the procedure Quantum has spelled out? If there is and doing it any other way works and makes you feel better, then go for it. 
I do it the "Quantum way" but only because I tend to turn on the "main" power source last, anyway, no matter what equipment I'm working with. Even if Quantum had not said anything, I still would power on the equipments in the same order, with the battery pack being turned on last.
