I want to try 3 ball tote bags again since I'll be flying and it'll help it be cheaper flying with those. The only problem is it caused me to have strain and back pains when i was carrying them around. Has anyone else ever had this problem and found a fix for this?

Sorry I forgot to add I was talking about the 3 ball tote rollers

I prefer the 3 ball roller-totes. They are compact when compared to other roller bags.
The only "problem" is that they can be a little awkward when using the rollers due to the fact that the wheel base is narrow, which can cause them to tip to either side at times. Otherwise for me, they represent a decent compromise in bulk and portability.
