I just used the standard .065" thickness tubes. I had some tell me to use a thinner tube, but for the minimal difference in weight and the added safety factor of the thicker tubing, I thought it was the way to go
Here's a few more pics...

That's great! Thanks for sharing. I foind a carbon supplier that has the tubing I need, finally (only then in metric sizes, but that 1/10 pf a mm won't make much of a difference...). How's the steering with that 650 b wheel?
