I have a few of these and they are awesome. on a few occasions, I have even put a Sportube inside of the Burton 185 Wheelie bag so that when I met my family out West, I had two carriers for the return trip and the extra gear I picked up on the way (Sherpa my kids newly purchased skis, etc.).
The Burton 185 bag is actually able to handle a 190. I used to move Tanker 187 and Rossi WC 190 (at the same time) in those bags.
The skate wheels are hard to replace, though.
