I suppose you'll be OK with either. 11 doesn't require anything special. Both are directional twins. Which are OK at switch riding. A true twin would be better. I had 2 fat bobs years ago. That's why I voted fatbob
They ride nice?
Like I said I don't know much i just really want to end up with a solid board that i'll love to ride as my first board
Also what do you think of the size difference? k2 is 155 sims 158
