I'm not sure what is different with the IQ Tour Solid but the cover seems softer or something, it definitely lane shines incredibly fast and is a ball you really have to clean after every use and almost everytime out refresh the surface with a 2000 pad. If you keep up with the ball will last and roll well, but i've found (I'm on my third, burned one out and had a bad layout on one) the ball needs a ton of maintenance compared to a lot of balls on the market.
