Seeing this makes me miss mine, mini ramps really are soo much fun.
Here's a really nice edit on a Winkler DOS (unsurprisingly) from Emma M. Not the best tricks I've ever seen on a miniramp however far from bad stuff either, and the way it's put together makes it a really nice watch even if you wont be jawdropping from the tricks. Good stuff!
