I really need to get another Shock (or two). I've bought a ton of balls since switching to 14 - just none from Motiv (and I had a lot in 15). For some reason, I keep putting it off. Same with the Storm Hy-road. Owned a 15 Pearl, and now own a 14.
As for the Show Off, the box finish was way too strong on our house shot - at least how it has been playing. 4000 was better. Last night I tried 2000 + Reacta Shine polish. Definitely an improvement, but the ball is still forcing me a bit left of where I normally would prefer to start play. A ton of ball for the price point.
