I have the IQ Tour and the Web Tour. The two are very different balls.
The Web is simply a ball designed to handle more oil. The Web’s NIB cover is much more aggressive at 360/1000, but the IQ, even at the same grit, doesn’t compare. I can use the Web on volumes of oil I would never consider the IQ on.
When you think of the IQ, think of the GB2 as the more equivalent ball in the EBI line. That will help clarify thinking.
