I have a Loco Motion with ~20 games on it. It's drilled 20x4.25"x50 (pin below fingers with CG kicked out to the right at about 3:30 o'clock in relation to the pin) with an extra hole 2" down the VAL from the midline. The layout was specifically recommended for USBC Nationals in Baton Rouge. Surface is factory (1000-siaair under Rough Buff under Factory Finish). The ball wants to start up early (due to the 20-degree drilling angle) but still makes a good turn on the backend, with excellent continuation through the pocket. I bowled a tournament and practice on the nationals shot and did well each time: 4th in the scratch tournament (should have made it to the finals; my bad for not moving left in the semi-finals; not the ball's fault). The Loco has a core similar to the Perpetual Motion and Aggressive Motion but marginally higher RG. With more standard drillings (60x30, label leverage, etc.) the Loco will get good length with strong back end recovery. It's a good fit with my 60x3.5"x30 Perpetual Motion and 60x3.5"x30 with a P2.5 hole Aggressive Motion.
The Loco has a stronger coverstock than the PM but not as strong as the AM.
On the house shot, I have to move right, more parallel to the wet/dry transition as the ball responds quick to the dry.
Later on when I move left, the Loco exhibits excellent recovery from deeper lines fed to the track and outside the track.
