I'm in the same boat you are size wise... same weight and hight.... Have you ever wakeskated before?... any thoughts into what kind of skate you are looking at, company wise? wood or composite? ... In regards to size, its all personal prefernce, but I find for me, being as tall as I (we) are, I find a bigger board is better for me... the smallest I would ever ride comfortably would be a 41 ... but I like to keep it in the 41-43 range...
