Tumi

Full review
I have ordered Tumi Rolling luggage in several sizes, I order a piece a year to be able to afford it. It is the most balanced luggage I have ever tried, fully packed, I could wheel it through the airport with one finger.
I looked at many different brands, and the Tumi just seemed the best for someone who travels alone a lot and tends to pack the kitchen sink for a one week vacation.
Negatives? Price, price, price. There are few if any sales, sometimes you can get a bonus of a small carry on bag with the purchase of a larger bag. Tumi doesn't allow anyone to discount their product, so, if $$ is an object, try ebay. Well worth the money however.
