I was looking at a video Clare put up on youtube. I understand she is showing students what to do etc. but still, it's 18 seconds between looking up and letting go. If the smb is going to be controlled when you inflate it, then why not look up just before you let go ? I know I'm being really pedantic now so don't mind me, I probably need a beer !
Here's the link, maybe Clare could give her 2 pence worth
