Okay - after getting so annoyed I gave it up for a few months, I'm back trying to get through the bigtop tent in the Meat Circus. The problem I'm having is the knife thrower wheel after Raz jumps across the hovering 'cutlets'. I can get him to hang from a knife and all - but he simply won't jump the distance to the next meat platform, he comes up too short. I've tried to activate the levitation ballon in mid jump, but it doesn't seem to work. What's the catch or trick here? Thanks in advace!

(I was able to bypass the first knife-thrower by levitation jumping up, rather than riding the wheel.)
