Tune is 1 base, 2 side; last tuned in February, so it could use another before the season of course. To my knowledge the board has not been ground.
I can't speak for how much it was used before I got it, but as I've said above - and as the pictures eaglez linked to show - the board was in almost-pristine condition when I received it, without any marks besides a couple topsheet scuffs from bindings/boots. It obviously wasn't used much. Like I said, I rode it for 5 separate days, but I always switched to my BX board in the afternoons; I would estimate I put about 2.5 total days of riding on it last winter.
"East coast board" depends on where you are on the east coast, and what hills you're riding. The side cut is variable - just over 13m - which means you have some flexibility to tighten it up or let it go. It's just that where I am in Nova Scotia the available hills are very, very small - think 450-600 feet of vert - and the trails have lots of narrow areas. I felt I just couldn't use it like I thought I should.
There are lots of great hills on the east coast of the US though, as well as in Quebec. I took it to Saddleback in Maine for a couple days last year and ripped it up. But I couldn't justify keeping it for that sort of once-a-year event; I needed something a little smaller and a little more versatile for what I'll mostly be riding.
Feel free to email me if you'd like to know something else....
