I've had the RS Convertible Carry-on for about 15 years, which is still in excellent condition, but think it might be time to go to a rolling bag. I've been contemplating two vs four wheels, and think that two works better for the kind of travel I do.
Have any of you gone from using the Convertible Carry-on to the RS Rolling Carry-on? I'd be interested to hear the differences in capacity, since the exteriors look similar (they have the same outer and side pockets, for example). I'd also like to hear from anyone who owns an RS Rolling Carry-on about the durability of the bag overall, especially regarding the wheels and handle. Sadly, no one from any of the travel websites or other places, such as Wirecutter, ever review RS bags, so any feedback people can give me would be appreciated.
