Thanks for the replies.

Interesting about the Mini being a children's suitcase because I was at the Rimowa repair shop yesterday and I asked if they had anybody bring in the Mini Trolley for repair and the guy mentioned he thought it was a kid's item and therefore inappropriate for a adult. He didn't have any brought in to show me, and the local Rimowa shop didn't have any in stock (not that I'm crazy enough to buy one in China).

Anyways I'm now in a cheaper place to pick one up, but to me honest, I think I'm going with the Business MW. I think I'm addicted to the effortlessness of the MW luggage now. Now the hard part will be picking between a Stealth that I like or the Titanium which I already have a couple of (also the latter seems more scratch resistant), though I've never used the Stealth so that observation is based purely on seeing other people's bags.
