I've pretty much done all the "trick layout" experiments (probably even invented a couple) but I hadn't drilled a 315 layout (link:
http://www.bowlingknowledge.com/tips/mario/mario_315degreelayout.htm) yet.
I finally did this week. I found a short-pin Storm Attitude Shift, applied this drill pattern and then polished the stock grit (2000) with a heavy application of Storm ReactaShine.
I was able to get both the pin and the CG under the finger line, and drill the fingers deep, which coupled with a low starting top weight, kept me from having to drill a weight hole.
Tested last night on fresh medium THS. The drill pattern does exactly what it's advertised to do -- it produces a very mild arc on the backend and helps tame down the reaction without hitting weak. I was able to continue to go up the right side even after the lanes broke down. As an added bonus, I also retained a little bit of that Storm late-lane punch right at the pins to help kick out the corners.
With this drill pattern, the ball was a good bit weaker than my 900Global Break Pearl with a double-thumb, pin-over-bridge drilling. Both balls are at 2000 plus polish, but the solid Attitude Shift was still cleaner through the heads than the pearl 900G ball. The Attitude Shift almost acts as if it's being magnetically pulled toward the gutter through the front half of the lane, then changes to being smoothly pulled back to the pocket. Watching the graphics closely, you could see the point at which the ball appeared to "flip over," but without a really violent, uncontrollable flip.
Summary: Great control drill.
