$40 for a blue dot is not cheap man. It's a plastic ball, for
goodness sake. Pancake weight block, does nothing. Besides going
straight that is, which is what you want.
My opinion on spare balls --- get one at least second-hand, it
doesn't really matter how many times it's been plugged, it's
PLASTIC. Got my bluey third-hand, it works great. Unless, you're
forking out money to get a real nice one, like an ebonite clear
wolf, or it's part of your starter pack, bo pian. Or if you're big
on aesthetics, then... *shrug*. Some people must look good to feel
good to play good.
