I have the 4-ball roller and I love it. I previously had the Hammer 4-ball in line roller and I hated it. The compartment in the Hammer bag where you had to put the 4th ball was not sturdy, and the ball was always off-center. Also, the zippers ALL broke off of that bag.
The Lane #1 bag is great: tons of room for storage, smooth rolling, and you feel like all of your equipment is very secure. You can remove the top and use it as a 2-ball tote.
I have room in my bag for 4 balls, shoes, all extra heels/soles, a bottle of cleaner, a wire brush, a pile of quarters, a deck of cards, 2 boxes of tape, 2 towels, a bottle of Aleve, and extra pair of shoes, and there is still room to spare.
I haven't had any problems with the zippers breaking, and I have never lost any equipment out of any of the pockets because of it falling out. Seems like a good design, and I don't think you could go wrong with this roller.
