Hey, what's up man. I'm one of the guys behind EP - thanks for the interest.
The Vapos were developed as our park ski replacement for the Spinners, which are going to be phased out next year. The main difference between the two is that the Vapo is camber underfoot with early rise tip and tail, while the Spinner was a traditional camber ski. We're really happy with how the Vapo performed last year, super light with very low swing weight but stiff enough to hold a really good edge in the turn. They're really fun. We've even had people buy them for pow. We'd be happy to try to line something up for you to demo them, just shoot me a message. Next year's are going to be pretty much the same ski, but just a little flexier, with a more rounded tip and tail and a smoother rocker profile than last year's.
Regarding that other thread with durability concerns, sure, there have been some difficulties which we are constantly evolving to address, and definitely aren't trying to hide from. Any ski that has had issues has been warrantied. Park skiing beats the shit out of skis - even companies who have been building skis for decades put right in their warranties that park skiing can void your warranty. Topsheets are really tough to keep in good shape - we started out with PBT, which is common on snowboards but ended up chipping to easily on skis which get hit with edges all the time. Then we moved to nylon, which was better but still not up to the standard we're looking for. For this year's production run we're moving on to another kind of nylon which we think is going to be pretty bomber. There were also some delam issues resulting from overpressure on the press which squeezed out too much epoxy, drying the fiberglass too much. Of course it's always hard to keep edges on skis, so we're figuring out ways to address that. Again, it's all stuff you have to learn the hard way when you're starting out on your own. Starting a ski company isn't easy, but it's a ton of fun and it's what we want to do for the long term. We're taking what we learn to always innovate and think of ways to make better skis. You can follow our Ski Builders thread here http://skibuilders.com/phpBB2/viewtopic.php?t=3748
to read about our startup and what we're up to now. We're going to keep it up to date with all of the stuff we'll be playing around with, including new shapes, innovations, etc.
Again, thanks for the interest, and we're always happy to let you demo some skis if we can work it out. Just let me know.
