I see what you mean and mine is the same. I carry all accessories, cords, pedals, and laptops in a plastic tub, which goes from my Rock-N-Roller to the floor of the venue. I pack it carefully with the fragile items on top. I probably will get a sleeve though.
I was wrong about different prices being a possible cause of any flaws. I was thinking I paid more than $94, but didn't.
All in all, am very pleased with the Pro 12.
