When I flew home from New Orleans for the ABCs, the woman at the Continental front desk told me that 3-Ball Rollers are allowed, regardless of their weight. She printed me a copy of their limitations and it reads rather vaguely. It can be interpreted many ways, but the customer never wins these battles.
I look forward to dropping another $50 when I fly out Friday morning.

Why does everyone try to make it harder than it really is? Overthinking makes the game that much more difficult.
