I disagree I'm a two wheel guy, spinners annoy the heck out of me, especially if standing you're on a slope, the bloody things roll away from you, whereas a trolly won't. If you're pulling them the bigger trolley wheels work better than the smaller spinner wheels, they also work better over rough ground and broken pavements. Also if you're running for a gate the trolley is a faster suitcase to shift than the spinner.

I have a spinner Salsa IATA cabin, used if for a year then went back to a trolley. I now have 4 Rimowa cases, 3 trolley and one spinner. None of my trolley wheels squeak, neither does the spinner.
