I put the factory Storm/Roto 4000 finish on mine and its stupid good. In my house shot league, I am on very nice AMF synthetics with a typical 40ft wall and the Hustle INK is the perfect house shot killer.
It is WAY stronger than you would think being a HP1 ball. I think you could have a couple of these with different surface and drilling and have everything you need for the casual recreational wall shot league.
I agree with the comparisons to the iQ Tour Solid. It's not as early as the iQ but they are similar. I'd say same surface and drilling the INK is a few feet longer. THis makes sense as it has a weaker cover.
In my league, when the shot transitions inside, the INK to too wild off the spot. I need to get out my iQ Tour Pearl and control of the backend reaction.
