I don't have a big one - I have a 20" wheelaboard and a matching expandable duffle bag that can be scrunched inside the wheelie but holds almost as much as the wheelie when unzipped. I love the colors, and I've received compliments on my bags, but I don't think I would pay full price for them. They are very strong, but not indestructible, and after one trip, there were some minor scratches in the alloy-colored rubber buffer spots, and also scuffs in the ballistic fibers which are now visible when looking at the wheelie from a certain angle. Also, they use some sort of foam padding between the exterior nylon and interior lining, which, on mine, was apparently unfolded because you can see these small, faint vertical indentations running half the length of the top of my wheelie. Not a big deal, but not what I expect out of such luggage - and I'm not even all that abusive with it. If you can get Tumi on sale, do it - otherwise, I really like Ricardo Beverly Hills which has gotten better over time, IMHO.
