the hype for the surf-tech boards is that each shaper makes up to 10 versions of his boards- tries them out, and then decides which one will be the template for the final epoxy board.
They are infinitely reproduceable- if you lose your "magic board" you go buy another exactly the same. You can even leave them at home- fly to Bali- and rent the exact same board there- surf it- without the excess baggage etc.
I'm loving mine-after 15+ yrs on traditional shaped boards through different local shapers with very variable results, I prefer the reproduceability and range of the epoxies.
Downside is the expense, and they "feel" different underfoot to the polyester boards- less flex, and don't transit as much vibration through them- they feel a bit less "alive" (don't know how to explain this one) getting onto them from the polyesters.
My 2 cents....
