Forget what he said, it's all about what you wanna do on your skateboard. Are you in it for tricks or do you like to cruise? Me i'm a big cruiser. I ride a Santa Cruze and it's so sweet riding and carving on the streets.
If you wanna do tricks by a good quality skateboard. Don't buy a Wal-mart twenty dollar special. Not that it takes a good board to ride good ,but you wanna make a good investment on the things you buy especially if you plan on being safe on the board.
I know i dont want my board to brake halfway down the hill. But yeah just choose your style kid. If you wana cruise buy a long board if you wanna fall and bust your ass buy a freestyle board, it's all about being comfortable on it don't force it or you'll hate it.
