We bought a couple of the convertible bags for our trip to England and Ireland this summer and I was amazed at how much they could take.
However, I don't like it for business travel, as I usually am travelling alone with a heavy computer bag, and a "rollie" would be a lot easier. It also looks relatively casual, and I like to be a bit more polished while travelling for work.
I'm looking at both the Ravenna and the Rolling Carry on. I've read several of the threads here comparing them, and it seems like they are both good bags, with features that give extra points, depending on the particular traveller.
Sometimes I want a carry on if I know I've got lots of connections and no "wardrobe slack" for the next day, but if I can, I check. I also loved the way the convertible bag I have goes from overhead-friendly to oh-my-god capacious when expanded--I think both the bags I'm considering have the same ability to expand. My business travel is all North American, which seems to be more flexible about carry on sizes.
Work clothes would involve a suit jacket or two, and probably 3 pairs of shoes. I plan pretty carefully for coordinating, but will still need bulky items like jackets and dress pants.
With the heavy computer bag, I really would like a main bag that will take the computer slipped over the handle without tipping or shifting.
I think I've talked myself into the Ravenna, but would love feedback from those who use either bag.
