I've got a feeling that there is a sheet similar to maffioli (not convinced this is the right spelling) but doesn't absorb as much water, in fact it repels water. If you know of such a product could you remind me of the trade name. Also, if somebody is using such a sheet is it as flexible as normal maffioli or dyneema etc. In other words would you recommend it for Spi sheets?
Many thanks
Mark
