In reply to Simon:
> ...top out on things like this?
now I've stopped giggling at the comments about the goon (why is it your head inflates when you're doing hard moves?) and "the kid", I'll have a go at answering the question...
I've seen (and done) 3 main approaches to toping out on big sloper tops:
1. keep slapping onwards until you realise you're lying on the top and you feel like you're climbing the floor
2. throw a foot over and flap like a beached whale (helps to wear jeans for this - more friction)
3. turn one or both hands round to palm a reasonable sloper and elegantly mantleshelf the last move.
oh, 4 - give up, pronounce yourself at the top, and jump off (if carried out with sufficient aplomb you may even convince yourself you've done the problem)
