crawford:As I understand it, your arm muscles are more efficient/use less energy than your larger leg muscles. Pullling and gliding will help your gas usage in high flow caves. If you've ever done it you can feel the advantage of pull and glide versus kicking against strong flow.
Of course, this is a discussion for us too poor to buy a scooter :11:
Crawford,
You're so right.
I told you, if you ever come and visit me, you can borrow my scooter.
