Gato,

I'm thrilled to learn you go down that route.

I'm very interested in the results that you obtain that way and I have very high regards for the spirit to just try it.

You there are no other objections then I suspect that putting carbon on both sides (inside and outside) is best when compared to putting the same amount of carbon on only the inside or outside. I say suspect as I haven't done a more thorough analysis in that aspect yet. My expectation is that you can then get away with a significantly thinner ply wall. You be stressing the carbon fibres maximally but it is said that you can do that with carbon without much ill effects.

Best of luck !
