anyone have some feedback regarding the longterm reliability of spinners? My trusty 26" Samsonite Silhouette 7 is in need of replacing after many years of service.

I've been looking at the 2 vs 4 wheel designs and I'm concerned that the complexity of the 4 wheel design might reduce the reliability of the bag. The 2 wheel uprights still seem to use the tried and true inline skate wheel design, a hard rubber wheel with a single bearing case inside. The spinner bags all have two thin wheels on each corner and also spin on their axis. While these are very convenient and easy to push around, will the bags last as long as the uprights? The design seems a little fragile and not sure if it is up to my sometimes brutal style of travel. For example one trip might be 10 hotels in 14 days in China etc, traveling via air, train, car, bus etc, so tons of handling by ever more disinterested handlers.

Thanks in advance
