I have an older standard, works fine up to 60 ish planes for it so far and no issues.
I’m not hugely fussed about how easy it is to get around airports, more the protection for the bike inside.
The ease of movement does actually mean it’s handled better in my experience, I’m less likely to fling it around as it’s easy to haul with a few other bags.
My mate fits an xl trigger 29r is his fine too. The wheels support it vertically, the rigid base stops the stays/fork squash and the straps mean things don’t move and rub. I sometimes throw a towel or sheet in but that’s it. Can’t see much more the pro could offer.
