Polystyrene foam too by the way (Marko 2.5#.) My last longboard was glassed in 5oz E and UV cured polyester (polyurethane foam.) It’s lasting really well, so I was thinking of 4oz S? Should offer the same strength as my 5oz E if it’s epoxy shouldn’t it? Little bit concerned about S cloth and delamming through memory issues though. Any thoughts, suggestions or large sums of money are always welcome.
id say double 6 deck with a patch
6 bottom minimum with patches on the fin boxes
