Thanks for the input guys but I don't have the space nor facilities to make such a large tube here. Hell, I have trouble finding somewhere to put this one. I've asked her to quote on a tube using the mould she has (298.xx mm ID), using 6k 2x2 twill weave 30% resin, 2mm thick and the cheapest shipping
She quoted weight at 3.78Kg earlier.
I think the mould fee was just going to be a xmas bonus for them
