That's a lot of movement for a bag IMO....I think I would be too nervous

I do 52 with the sam Gator case on wheels you have for my PA 4X-76 and still get antsy when fellow-shippers "help" me and grab the keyboard while I'm not looking and take it to the SUV......

Especially after the Assistant Pastor took my acoustic out to the SUV & the wifey backed up into it after he set it down...He yelled for her to stop before damage was done.....

They told me 6 months later........
