hi, i'm a beginner right now and i'm about to purchase my first board but i'm a little lost as to what to get. I live in san diego, ca with wind speeds about 10-15 mph. also i weight 168 and i am 5'11 and i've heard that i should get a 135/140 x 41/43 board for my weight. also i've heard that a litewave 179 / 181. but i was curious is there anything other specifications i need to know about when i purchase a board?
