Back on topic - I started with Columbia for years, switched to Lanemasters and Track recently. As far as coverstock durability, there is no match for Lanemasters equipment. As for overall performance, well, on this forum, you will get little argument that Track is what it's all about. Having said that, it all depends on your game.
I have had no problems with any Track equipment as long as I clean it VERY regularly. I have had no problems with Lanemasters equipment whether I clean it or not.
