Can't say I fully learned it, but I landed my first bluntslide the other day. The spot was this short, noping QP that sits on top of a bank, shaped like a half-volcano.
So charge up the bank, skid into the blunt on top of the quarter, (BS), slide 2-3 feet, pop-in forward on the other side of the volcano.
I stuck one w/in 10 tries, and got another on camera w/in another 10-15 tries. Haven't learned anything that far outside the bag in a while, I'm still pretty stoked on that.
Wax actually helped me for once!
