Left hand and Right hand ball layouts are mirror images, there should be no problem laying out the ball.
The Bully is an early
rolling ball, it is designed to be that way, so seeing a lot of roll should be no surprise.
When selecting a Bully to arch in a different pattern, you need to select one with a pin-out distance around 4 inches or more. The shorter the distance the earlier the roll.
I drilled up a 4.25 pin-out, and set my PAP to pin at 3.375, then used a Torgerson 73 degree layout, with a deep X-hole below the equator. It is a skid snap drilling on an early
rolling ball. If the oil is there, it works perfectly. If it gets dry it will hook off the lane.
I shot a 711 with it last night in a tournament. Over the length of the tourney, I only moved a total of 7 boards, to cover all the transition for the night. I ended playing from board 35 out over the center arrow, and snapping hard into the pocket.
I was very pleased with the versatility I witnessed last night from that ball.
The thing about it is, having the drilling match your style of play. Drilling pattern wont make a cranker out of anyone. A cranker can crank a house ball for a hockey stick hook. What I have discovered on my Bully so far, more than any other ball I have thrown, is that I have to force myself to let the ball do the work. It will over react so easily to a squeezing grip, or a snapped follow through. You have to really let gravity control the shot on the Bully.
