Well, I rode five hours without a break, so the board must be alright. It took a bit for me to get used to it. At low/medium speeds it seemed to want to bounce like a boat just getting on plane, but at high speeds it was MUCH easier to ride than my Raygun. Much stiffer and 4cm longer made it a lot better in the chop, as well. On the Raygun I get bounced around if it's not smooth. I was also surprised by how much pop it had --maybe because of the flat tail.
I was happy with the groomer performance. I debated even getting the board (despite the year end deal and money from a dude putting a dent in my car burning a hole in my pocket) because I just started last season and have to ride some groomers because I can't handle the really steep stuff yet, but the edge hold was fine when I did get back on the groomed stuff. Maybe a little more effort to initiate a carved turn, but it locked in well once it was there.
