My rep let me ride them at the end of the season.  I get a chance to ride lots of skiis (i work at a shop and am sponsored by  another one) so I get a chance to ride lots of skiis.  In my opinion, they're the most versatile fat skis around.  IN the east I'm not sure how often you really need a ski like this.  Last year's Tweaks were a lil squirly in powder.  This years sould be much better but if there's a lot, the wide underfoot of the Stomp is key (especially landing fakie and learning rails).  If you want a more versatile ski for the east that actually carves nicely and is really responsive, hit up the Tweak.  If you're doing lots of backcountry airs, get the Stomp.
Later.
