The lock is stupid fun to throw and really impressive at how much controlled strength it has. I drilled one up 4x4x1 as I really like this setup the first time I drill a ball as it gives me a solid base to work off any possible re-drills or surface adjustments. Now my game is in the dumps right now and I'm slowly working out all the kinks, but this balls most impressive feature is the way the ball clears the heads and midlane without even a hint of jumping too early.
I now bowl two leagues in two houses with two different "house shots", one is a typical blocked up wall of bounce typically seen as the normal "THS". The other is a beefed up house shot, flatter with more oil, typically a ball swung out to the 5 board will hit the 6-10 in the face. Every ball comes back with full rings of oil on them ALL night long, so you can typically just keep edging on the line oil and only move 5-6 boards a night at most. The Lock eats up the heavier shot like it's nothing, controlled sweeping hook great continuation. On the lesser shot, it holds steady and makes a strong move to the pocket on the back end and really allows me to play a different part of the lane than 95% of the other bowlers in the league. Versatility is an understatement with this ball, and it seems you are seeing the same thing.
Pearl.....lock....yes please! My favorite ball of all time was the el nino 2k, I see similar motions with my lock now and I'm sure a pearl would be almost identical to my old 2K
