The new 7s epoxys are ok and a good option I guess if you are travelling but just don't have the feel of the glass version.
See boardlady's opinion on single skin glass-epoxy construction:
boardlady.com/anatomy.htm"single-skin fiberglass over EPS core boards. I don't get it - all the extra cost and vulnerabilities of Epoxy, with mechanical properties worse than the old-fashioned glass board. At least those did not soak up water..."
Um, I'm not sure what "boardlady" is using for her testing of mechanical properties, but a properly cured epoxy laminate should have much better mechanical properties than the same laminate lamainted with polyester.
Couple more points
- ePS soaks up far less water the poly cores, which is why they can be used for coolers
- Vulnerabilities? huh I'm lost
-All ester resins have a "recomended" mixing ratio this is not to be screwed with. Yes pouring in extra hardener will speed up the cure of the resin but it will also produce a sub par lamination because you will loose your consolidation time as well as poorer mechanical properties or a brittle lamainte. Not to metion the extreme danger of creating a "pot fire" where your pot/bowl/cup of resin goes up it flames, this is
very very dangerous.
There's a reason that all of the high end custom yachts are laminated with an epoxy system and not polyester
