I have been skiing for several years and decided this year to pick up snowboarding. I actually just bought a board boots and binding but wanted to make sure that i got what i needed. The was two different types of board same everything (including price) one was a cap and the other a sidewall construction can someone please tell me the difference. (i got the side wall) also i am 6ft 2" tall and about 175lbs i got a 163 board was that the right choice.?? thanks
