But I definitely feel like I could take a nap while cruising a blue circle or green square.
Uhhh...I think it's a good thing that you find riding down a blue or green is boring...it should be boring. Embrace the slayblad and step up your game until you are riding stuff that is no longer boring!
I haven't ridden the slayblade, but it sounds like you are just riding a board that is meant for much more than cruising blues and greens. Sounds like a great board to progress your riding skills.
I'm not saying you need to get better, I don't know you, but it sounds like the terrain is the boring part, not the board.
