When I see them making people with roll ons check them at the gate (f g hate that) I simply turn it into a backpack and wall on without a problem.

Yes, this was brought up here a few months ago too. With a backpack, you are less likely to be asked to gate check your bag.
This isn't exactly what you asked for, OP, but I will give you my recommendation:

Each member of my family has one of these, and we love to travel with them. Since your kids are teens, these will be useful if they are young adults traveling or in college too. I have kids in college and I know it was actually mentioned by several parents (on a facebook group for parents of my kids college) that there wasn't enough storage space in the dorms for the luggage the kid had brought. I was glad my kid's backpack carry on was able to be squished down and stored easily.
