Best Over Night Carry On Roller

My wife has the Samonite  72 hours 50 cm  but I personally find that the wheels on my Victorinox  are fantastic in terms of ease of movement although she prefers her Samsonite 

I bought one at Macys  for about Aus $500 but bought a second one in Sydney this year for $263

Combined with a Crumpler Flock of Horrors  bag  that sits on  top of the  Carry On   its all I need for  a months travel
