Has anyone tried out this Tactical Surfing?

The other day out in the wild of Social Media the Russian Systema Serbia was showing off their tactical prowess by surfing down a staircase which caught lots of attention.
Well, Mike the Cop on Facebook who always likes to try out new things, decides he wants to see how hard is it to do this tactical surfing and see if its worth doing.

What he finds out is that its easy to learn to do but reality is that it hurts (like hell) when you try to surf this tactical style down a staircase.
He may have done better if he’d lubed himself up with some slippery jell.
Has anyone try this yet?, (Hollywood is probably looking at this right now)
Let us know below.
