Grasshopper technique questions!

Having grasshopped my way from novice to nutcase last week, I made some major
breakthroughs, gradually refining my technique and learning to understand the
physics of the board, and my muscle reactions / aches, enough to get my board /
bindings set up really nicely.

Now..one grasshopper question on technique...

Turning from toes onto heels is fine at all speeds, but I had quite a few falls
at first turning from heels to toes, especially at high speed. The final
breakthrough seemed to come when I started bringing the back leg round more
purposefully as I turned from heels to toes, as I'd seen others do - really
consciously flicking it round as I made the turns. From that point, my crash
ratio went down rapidly. I was already OK with my body / shoulder / hip
movement and weight distribution, but this made an extra difference.

So, my question is, is the above something that most people do a lot, is this
correct technique (at medium to high speed - clearly you sometimes have to do
that, eg sharpo direction changes at low speed) or does my need to do this mean
that there's still something not quite right in my technique? It felt fine, but
quite tiring and took a lot of concentration. That said, it was only my second
week boarding, apart from practicing on indoor snow in the UK.

Many thanks anyone - I am one happy grasshopper on a board!
