Should I get all Pocketwizard TT5s or one TT1 for Nikon D3?

Hi,

The difference between the Pocketwizard MiniTT1 and FlexTT5 for Nikon is $20. I was thinking of getting all FlexTT5 for five strobes plus one as a controller.

Do you have the TT5 as a controller on camera and what are the pros and cons? I also have the SU-800 I can stick ont the TT5 instead of AC3.

I like the dual transmit/recieve capabilities of the TT5 but I'm afraid the antenna will break. I like the size of the TT1 but it also uses coin batteries.

Did you buy the TT1 or 5 for your on-camera controller?

Thanks.
