Here is some examples of the degree layout system straight from the Powerhouse Clinic. How to read this chart is as follows: The front degree angle is for what it does in the back of the lane. The second degree angle is what it does in the front of the lane. Pin placement is how the ball flares and the length of the ball. For example, 75 x 4 x 30 would be strong/angular breakpoint with a early roll. The 4" pin will make the ball hook up even earlier. The longer the pin the longer the ball travels. This layout is extremely strong and will be very snappy in the back end. So I hope this chart can help out Motiv nation out there and instead of going to the powerhouse clinic I am giving you something to go by to make your layouts easier.

That is a very vague explanation of the dual angle system. If interested in truly understanding the system use this link and read it a few times!

Bowl Great!

I may know where the confusion is coming from. One of our local pro shops has been referring to an old wall chart for years that uses the center of the grip as the point of reference for degree drillings. This gives you a completely different layout than the current dual angle system that most pro shops are now familiar with. The dual angle system uses the pin as the point of reference for angle drillings, not the center of grip. I'm going off the top of my head here, but I believe a 90 angle drilling using the dual angle system will probably put the MB in about the same position as a 120 degree drilling using the old wall chart. This is a rough estimate of position. The link below will take you to an image of the old chart I am referring to. http://cdn.bowlingball.com/images/conte ... 3-bias.jpg
