Is it a bird? Is it a plane?

I think it's interesting to look at the differences in technique between different sailors. For example, Haircut clearly doesn't slide his hand up towards the mast before the flip, which apparently is a complete and utter no-no, yet he still manages to make the whole thing look extremely fluid, every time.
I slide my hand up (when I remember) and am lucky to wobble around and keep my hair dry... so does that mean that sliding your hand up to the mast is the wrong thing to do?
So many times I think that advice on where to put hands/feet for particular move is just the placebo we need to really give it 100% concentration and figure it out for ourselves... if someone says to me that the only way to gybe properly is to wear a yellow life vest then I'll be out there next week with a yellow life vest, and probably do a better job than if I hadn't been given that advice. The mind is a strange thing...
I know what's wrong now! Where did I put those hair clippers?
