When using the dual angle technique, is it best to use angle sums that match your style or should you choose the angles that will allow the ball to do what you want it to?

What's more important in determining ball motion, Pin to PAP distance or the two angles?

How would you order characteristics of the ball, surface, and layout in terms of priority in determining ball motion? That's how I'd order them but I'd like to know other's thoughts.

POLL: Is it better to use similar drillings on most of your equipment and modify the surface to find the right reaction, or to use different drillings while modifying the surface at the same time(which do you folks do)?

nice question.. I will be interested in the replies.

I think pin distance from the PAP is the primary and most important decision when deciding what you want the ball to do. Degree to VAL and degree to MB are secondary.

From my experience. A ball is best drilled with layouts that go along with the balls designed reaction. Cant make an early heavy hooking ball a super skid flip ball and you can't go the other way.. (sometimes you can with surface mods and exotic drillings)

Also, I think I have figured out for me that it is best to drill most of my balls pretty similarly and let the design of the ball do what it is going to do. Example.. bad experience with a cell.. wanted a earlier, smoother, heavy hooking ball.. so I drilled my cell pin down and 45 deg.. didn't work.. I think it was just too much of everything.. I should have drilled it pin above bridge, 5.5" to pap, 60 deg mb like all the rest of my stuff and let the Cell's core and cover provide the smooth and early hook.

I'm wondering why Pin to PAP is the most important factor in drilling a ball. Not that I don't believe it, but it just seems like the amount of length and backend you get comes from the angles. Does Pin to PAP more or less determine the strength of the layout/ball? If that's the case, then it's easier to believe.

It's definitely true that you can't make a ball do the opposite of what it's designed to do, but you can sure modify the length/backend and surface to get close to what you want. It's always easier just to get a ball designed for your intent though.

I'm not sure what I should do layout wise. At least for the Pin to PAP. I could see myself using similar angles but changing the Pin to PAP, depending on the ball and what I want out of it. I've used different pin positions ranging from 2.5" to 5.5" and I haven't noticed any particular pattern in which ones I've had most success with. I've had two balls around 3.5" and I disliked one of them, 3 balls around 4.5" not really caring for any of them, and 2 balls with 5" or more and only liked one. So I think it's more a matter of matching up to the ball itself for me. But for some reason I like the idea of shorter pins.

yes. the pin to pap determines the strength of the layout. And length of the ball. One way to look at it is the pin length from PAP sets the power and the angles determine how, and to some extent, when that power is used

At 3 3/8 from the PAP this is the strongest position and creates the most flare. There is the most flare at this point because the core is at its most unstable position. As you go longer you will get less flare and a ball that goes farther down the lane before it hooks. As you go shorter you will get a ball that has less flare and wants to hook sooner. Farther away from the pap will normally increase the rg and closer to the pap will reduce the RG. Higher rg will rev less for a given force vs a lower rg that will rev more for that same given force.

check this out.. it explains the pin from pap pretty good... When they say "track".. think of 6 3/4 from the pap...
some of the static weight and mass bias stuff is a little outdated but it gives a decent general understanding of what happens.
