We have travel pro, too. We have two 22" roll aboards. After 100+ trips (and probably 50 miles on the wheels), we needed to bring the first one in for repairs - zipper in back and retractable handle. It came back from shop as good as new and it cost nothing to repair. The second rollaboard now has well over 100 trips on it. It has noisy wheels and a retractable handle that is beginning to not work properly; we will take it in for free refurbishment soon. Neither our 29" or rolling garment bag have enough trips to make an assessment; but they are both performing well and are not too heavy.

One advantage of travel pro (and I believe a feature you should look for on all bags) is that all handles are screwed in versus using rivets. Screwed in handles can be easily repaired while you have a problem with riveted handle. After disembarking Mariner in Singapore, my mother noticed that the handle was torn off their large bag. A quick call to concierge, and a minor repair fee, and bag is as good as new.

Have fun researching and let us know what you end up with.
