I rode the couch potato for 2 years. The poly version of the CP is glassed heavy, which makes it difficult to get going. Only the lighter EPS version will get you into waves early (depending on your paddle strength, of course)...but, personally, I still wouldn't go over the Lost volume calculator's recommended size because the tail gets so wide, it starts making turns difficult. Here's my full review of the Couch Potato: http://www.swellinfo.com/forum/show...-quot-a-review&p=203192&highlight=#post203192
if your an average surfer or better...the key to a small wave board is to pack more volume then you have on your shortboard, at least 10%, in as small of a package as possible. Generally that means much thicker, shorter, and flatter. The shortness gives you the maneuverability. I have seen to many folks riding grovelers with a ton of volume in a longer package, tho if beginners is a good thing...however if your average or better, you will not be able to maneuver the board, you may as well buy a longboard. When its knee high to thigh, I have no problem maneuvering the board like my shortboard...its a 5'4" and packing 34.9 liters.
Nice, that sounds about perfect for what I am looking for. Honestly the size of a longboard is a deterrent too, I would have to get roof racks and I hate roof racks.
On a side note, I'm pulling this beast out of retirement. Someone gave it to me long ago, I rode it once and the fin broke off. Other than a fin and some patching it still lives.
