roomy
Buddy gets these and is pushing these in my pool hall. He uses the exact one as shown in the link and he fits a ton of crap in it. The funny thing about that is, he cut off the top handle so he could fit it in his locker. Actually the funny part is that there were bigger lockers across the room he never noticed until he watched me pull out my 4x8 and said "Man!, I should have gotten one of those lockers!"
The material on the case is something that closely resembles the material on my Taylor Made golf bag. It has tubes on the inside but the side tubes rise up fairly high where if you don't have joint protectors, you will have to turn your case upside down to dump out your stuff. A friend of mine has one that is a 2x4 and it seems to be well made, durable, but the deepness of the case seems to be a drawback.
There are some pretty deep pockets compared to an instroke or similar. I think this is going to be a new trend among the youthful players, but in a slightly enhanced version.
IMO, this couldn't hold a candle to a Whitten, Justis, etc.......
