I've been playing around with the latest CVS version and I'm not liking the fact that _every_ turn decreases rubber (maybe this is still a work in progress).

If you are just zig-zagging out in the open, jousting, mazing, etc. after a couple of turns your rubber is practically gone and if you touch a wall you go boom. I can see this is useful for servers that want to limit/disable 180s, but I think that the rubber shouldn't decrease if you are not turning against a wall.
Just my 3816 bits.
