Very smooth! I don't see how it could get much faster than this. Perhaps the only the way is the other route where you jump to the bottom from the top. But then again, perhaps not.
perhaps there is a way on the way back down to instead of going down the stcky and then bracking to slow down..,maby you could catch your wheel on the other sticky(the one you came up)and use it to sling yourself into the final downward tunnle without evan touching the middle landing? it looks possible to me anyway,I have gotten really close..
