If you're new to M10, start here. This is your basic all-around California shortboard; medium rocker, medium concaves, balanced nose to tail, works for the front or back foot oriented surfer, isn't overly dependent on perfect foot placement; fast, loose, holds a line, etc... People love this board and we've been making it for a very long time, with little adjustments all along the way. It generally works better in crappy waves than the Tomahawk or Millenial.
Everybody has so many models you don't even know what to get. How do you pick? We try to keep it simple by limiting the choices. To make it even easier, if you aren't sure what to get, just order a Magic Carpet. Isn't that what everybody wants anyway?
