EZ or Ace
If you're just getting into the sport then I would go with an EZ, it would be a great all around boat for you, one that you could grow into and a boat you could keep around for awhile. The Ace is a little more slicy, which makes it a lot of fun to learn cartwheels and stalls in, but not as forgiving.
Give a me call at the Mountain Shop in Ft. Collins for info.
