I second this. I have a Check-In M and 2 older style Topas 29". The 29" is right in between the new Original Check-In M and Check-In L. I don't really need a Check-In L but if I do, I would get the Trunk instead. It looks cool and seems like it would make better use of the space. I don't think OP you could go with the Check-in M... it is quite small.. more like a 3 to 5 nights trip type of luggage.
