Oh my, this one is proving tricky! So far, my best attempt has been to get through the whole sequence with three errors. These were a fail on the second whirlwind (it's normally an easy one for me, but I thought about it too much), a fail on the aeroplane of the first jumping stick (doh...no excuse for that) and a failed first attempt on the gunslinger. I've never previously worked on the gunslinger trick, so I was actually quite pleased to get it on the second attempt.
So, yeah, I know I've got it within me to do it cleanly - but actually doing it in front of a camera is another matter. I suspect that it can't be too long before someone gets it, though.
