I use a 22" rolling bag as my main suitcase and try to carryon as I don't like to check and wait
I also use a large purse/tote for personal items, phone, camera, baggy for liquids,etc
prefer to not have lots of luggage and focus on what is needed BUT when I need to travel last minute or not enough time to really think through what I need I find I end up with too much and use a bigger bag that needs to be checked
