I have a takayama Howard and should get the chance to ride the CI when my friend gets his. up front I think the two big differences are the the wide point is a little further forward on the tak and it has no concave on the bottom being roll into a big panel vee. The CI has a “tri plane hull” And some concave. From My Standpoint that’s no Bad thing. The tak is lovely if the wave has push and a decent face to draw line in but it isn’t great at generating speed on those race the section mushy days. I’d previously thought the same Board with concaves in the vee panels would be awesome. Seems Like the CI addresses that issue. Marketing genius aside. Devon wouldn’t Put his name on a bad board!
