I just bought and rode my WWW Rocker 155 yesterday for the first time. I wear a size 10 burton hail, and it was perfect width with the Sweater bindings. This was my first time riding a park board and it was a ton of fun. I've been riding for a really long time, and it's been years since I've had this much fun just by switching boards.
I've always ridden 158 to 163's and I thought dropping to a 155 would be a huge change, but I guess a 155 WWW is supposed to be similar to riding a 160 or something.
I'm really looking forward to trying different park boards and setups..
