In my experience, the best 3 ball bags are the ones with no shoe compartment and inboard wheels. If they have the outboard wheels they will store the bag on its side. Do not expect your bag to come out unscathed. Anything but 3 15# balls in the bags will go over the limit. Also, I have had better luck with curbside check in, I have had 57# bags go through without an extra charge that way.
