Lol @ snapping board comments... no way, unless it's a total POS! I do tail blocks in my sleeps (sometimes literally so) and on any type of surface - they are super easy and very fun/stylish.
And btw... how can you butter when you aren't moving?!?!
I'd like to see some vids of someone buttering with power at speed, none of this crappy 10mph spinning down a green cat track crap
So many people can butter, but 99% of them look ghay.
