I really liked Markphillipines last combo, and a few other things he threw in there. Made the choice tougher, especially that last combo. But after loosing count at how many times I have watched these and taking notice of everything. I believe Leon had more variety with back and front wheel (one combo with both front and back), Leon also had many nice touches to his run like the jump from the pedals ride in to hangfive then rebate back to hangfive then whiplash jumped directly to pedals. The cab peg wheelie ride in thing, and a bunch of other stuff. He also had some great turbine and pumping skills.
Mark packed a lot into his run, and that last combo stands up to the difficulty of Leon's stuff for sure, but the rest of Mark's run isn't quite up to the level of difficulty that Leon was throwing down.
In the end, I'm giving the win on this one to Leon Vignjevic.
