Yes I realize that. Been doing this a long time, I'm a ball motion and laneplay expert. Bowler style, layout, surface, lane surface, oil type/viscosity, lane machine, humidity, even which end of the house all factor in and all matter. But sometimes people try to overcomplicate things too much, and by and large, the Zero and Shock are very similar in reaction. I'd like to do a comparison video but I don't know anyone who owns both balls.
My Revolt wasn't enough on the fresh, but it wasn't at box surface either. In years past I've been ok with a polished Taboo, Sigma Tour, etc., this year the volume played much heavier than I expected. The shot walked into my reaction about middle of the second game on both sets, but at box surface it would have been perfect. Zero and Revolt have two completely different shapes. The Wipe Out also acts nothing like the Shock. Shock is a stronger ball overall, with a cleaner and more defined move on the back. Wipe Out is much smoother with a much slower backend transition. The Revolt ball motion is much closer to the IQ Tour Solid, even though again the numbers don't quite match up (differential specifically).
If I were you, I'd take a couple Tour Fusions, one at box, and one at like 2k or 3k. Tour Fusion and Venom Shock were the best two reactions I saw when I was out there. The LT 48 at 3k worked very well once the patterns started to break down too.
Eh, I saw the Shock and Zero on both patterns in Reno, and while both balls read the lanes extremely well, they both read them pretty similarly. Again, Shock was a little later and cleaner, Zero had a bit smoother read, but too similar to split hairs on.
For a few bucks less, the Wipe Out is direct competition. The Zero will keep a similar roll on heavier volumes where the shock will want to skate. If you bowl oj nothing more than medium, they will be comparable. But that is where I raise you, the Wipe Out.
Same bowler with the same layout? Not trying to split hairs myself, but these things matter. My Zero is too strong on this years Nats team pattern, through testing only. Im looking at more of a Wipe Out as the strongest piece I can pitch. Meanwhile, others can stand to throw more ball than the Zero. Its all dependent upon how a person bowls and how they lay these two out. You even said your Revolt was not enough meanwhile Zero's are working. So I would compare the Zero to the Revolt and Wipe Out to the Shock.
