Yep - all that info is going to get you there!
The two things I keep having to get myself to do when I am just not balanced or am not feeling it, (especially when I set up a video or something and watch to figure out where I am going wrong), are keep my body turned and head position looking where I am going to end up, not where I am going to grind. Every time I keep looking down at the coping, I end up not committing or staying on top, but when you know where you have to go and where your board is going to hit the coping, looking ahead where you are going to end up makes all the difference to me.
One other thing, especially on bigger transition, is although you want to get on top of the coping, to stay lower helps keep balance and keep you going.
If I start to feel unbalanced, silly as it might sound, I just go faster and stay lower and a slash usually turns in to a longer semi stand up grind anyway, but my grinds are definitely not how some people just sit on the coping for long distances or right around corners of bowls.
I was looking for pics and video of people like Max Schaaf, Peter Hewitt and others, but didn't really find a good pic showing what I mean, but to see Peter Hewitt can sometimes confuse people more, just because he can look all twisted up, but usually goes twice as far round on the coping than others in a given session. This one will have to do for now:
I also found a couple of decent pics from Omar Hassan, but the GIF from this blog might be one of the best to show one in his pool bowl, from Caught in the Crossfire (which in itself is good to see too) but this one is almost like a manual round the coping, if that makes sense.
