I have a Columbia 3 ball roller bag and i have had it for about a year and have had no problems at all with it.  It is made of very strong material and heavy duty zippers.  my friend has a 3 ball track bag and it has came unsewed or whatever you want to call it and also the handle just came right out of the top.

I had an AMF 4 ball roller when I first got serious, and it was a good bag while it lasted but after 1 1/2 years it started falling apart (handle broke, zipper broke on front compartment, part of wheel broke on one side).

I then decided to do more tournament bowling and got a KR 4 ball roller, and its a much sturdier piece than what the AMF bag was.  It also has more storage space which is what I really like about it, and after 3 years its still all in one piece with nothing broken.

All in all, if I had to do it over again I'd say piss on those wide, annoying, bowling ball busses and get me 3 tote bags.  I found out real quick when you are in centers that are not very wide in terms of walk ways or they are extremely crowded its a pain in the butt to weave your way around people. I also learned that all the people who do bowl in tournaments often mainly use tote bags because they are easier to move from one place to the next and alot cheaper too.  For someone that has a bad back or something though, the 4 ball bags are an asset, but to me they weren't worth the trouble.

If you are really into RotoGrip, look at their tote bags (unless you really want a 3-4 ball roller).  They have the most storage space of any tote bag I have found.  And their stuff seems to be good quality.

The one feature that I absolutely LOVE about my Roto 4 ball bag is that the lower bag has two solid handles on each side. It makes it SO MUCH easier to lift into the car. My Brunswick bag did not have this feature.
