I have had both of the styles. The first one had the shoe pouch and accessory kit on the side. The shoe kit slightly dragged on the ground wearing a hole in it. This is the only problem I have ever had with that style bag. I have used it 3 years in a row now to fly to USBC's and those airline baggage "handlers" beat the living crap out of that bag and it still is in one piece.
The second one or current style was nice with the extra pouchs on top. The kind and friendly airline guys broke the runner underneath on the first trip I took it on.
The nice thing about both is the wider wheel base. This makes cornering much easier.
I just bought one of the new Turbo 3 ball rollers. The shoe pouch straps on top of the bag. The wheel base is wider than the Storm/Roto ones and it corners like it has rack and pinion steering.
