Costco used to have the Wavestorm 5'8" "sushi" fish. I've seen the CBC ( California Board Company, although made in China ) 6'2"" fish on the internet, and it was way more than Costco's mark up.
If you're after a "better" soft board, the best is from INT Softboard ( made in the USA ). Catch Surf puts out some good boards too.
If you want a "Hybrid" Soft/Hard board, Surftech just released their new line of Soft tops with top shapers like Bill Stewart ( Stewart surfboards ), Donald Takayama (Hawaiian Pro Designs ) and Marcio Zouvi ( Sharpeye surfboards who Toledo Filipe rides for )

Look at the float volume on the 6'0" ! Should be plenty. I was thinking of getting the Sole 6'6" because it just makes the 2 meter limit to bring on the train here in Japan.
