I am a proud owner now for about three years of a tristar..... the best piece of luggage I could ever imagine.
I have packed the cubes using various methods..... usually a combination of rolling the clothes and folding the clothes.
My partner travels with a wheeled bag and will never covert and that is fine. We were looking at more effective ways to pack his bag. usually uses cubes and folders and a combination of techniques.
We decided to try the bundle method and were surprised how it worked.
I think it depends a lot on where you are traveling, for example if you go to one place and unpack the bundle method is a good option.
This led me to think about packing the cube for the tristar in the this method and wondering how others pack their tristar cubes
