I am planning to buy a Rimowa Salsa IATA case and a business trolley. Can anyone comment on how "smooth" are the 2 wheel version compared to the smoothness of the 4 wheels.

I recently purchased a Classic Flight IATA case with 2 wheels, and the wheels are not that smooth, especially when compared to the 4 wheels on a 29 inch Topas or a 29 inch Limbo. Classic Flight 2 wheels are relatively not smooth and noisy. Do not want to make the same mistake on my next purchase.

Thanks,

Ocean
