Pocket Wizard confusion

[TomSm]

I am confused about the Pocket Wizard choices for remotely triggering my camera. I have a Mini on my camera (Rebel T2i) and a Fex on my flash (430 EX II). From my reading, it seems like I have serveral choices to remotely trigger the camera. I would like to stay with the Pocket Wizard brand.

1. Buy an additional Flex and a trigger cable for the camera and use the mini a the remote trigger. I have read that this is a big drain on the coin battery in the Mini.

2. Buy an additional Fex and a trigger cable for the camera and another Fex for the remote trigger.

3. Buy 2 Plus II and a trigger cable for remote triggering the camera. Leave the Mini on the camera to trigger the flash.

Are all of these options viable? Am I missing something? Does one have and advantage over the others?

Thanks,
