In six+ years of skating, the biggest stair set I've ever ollied is 5. And that was once. Right now, I'm scared to ollie anything more than 3 steps.
I've been using the same board for 6 months.
In the past two years, I've had maybe 4 good days of skating where I actually try. Two of them have been in the past week.
I'd rather skate the local park than go street skating.
