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.
Similar point I was trying to make (without insulting anyone) when I said this:
I've found that I just have to push my riding harder, faster, steeper, bigger etc...to acheive that feeling of "vibrancy" as you call it...and the board both forces and allows you to do just that.
I was just amazed by how damp the ride was when I got stuck on a cat track getting from point a to point b.
