I have the K&R lane rover. It is an excellent bag. The only issue with it, and many others, is the height of the handle when it's DOWN. I drive a tahoe, so it's not a problem, but if you have a smaller car, it could be an issue for you. So before you buy ANY 4 ball roller, check out that piece of the puzzle.
I know that Brunswick bags are made by K & R - but I don't know about storm and columbia.
The storm 4 ball rollers that I've seen have a very annoying (to me) feature. Instead of the bottom opening with a zipper to the front, both sides open. If you constantly have the same thing in the bag, in exactly the same place, I guess it's not too limiting. But if you're like me, and what's in the main bag changes places a lot, it's darned inconvenient. In addition - if you've got your bag scrunched in with a lot of others, it's a pain to make room on both sides of it to get a ball out. Mine opens from the front.
