Great post in my opinion. When reading Mr. Kelley's thoughts on using 4 barrels I thought about whether he would have changed his mind if he saw today's equipment. It requires so much less precision in ball striking, and as Mr. YodasLuke said, power is far more important these days...
Kevin,
There is no reason to forego the 4-Barrel Stroke. Just use the Right Arm Throw Trigger (10-20-B) and see what you get.
Use Accumulator Combination 1-2-3 (think Drive and "Unrelenting Thrust" through Impact). Combine this Action with a Standard Pivot (10-12-A), and let the Right Shoulder take care of itself (any Active participation will qualify as #4). Also, experiment with the Non-Automatic Random Sweep Release (10-24-B) and note any difference in trajectory.
