Looking for some advice with respect to the dual angle layout for my new Storm Fire Road. (3-4 pin, 3 oz. TW)

(FYI - my specs. are in my profile)

The problem is in choosing the small angle sum/large angle sum when the bowlers traits conflict.

From the MoRich Dual Angle PDF (page 12): "Smaller angle sums should be used for: speed dominant players, higher axis tilt players, longer oil patterns, and higher oil volumes. Larger angle sums should be used for: rev. dominant players, lower axis tilt players, shorter oil patterns, and lower oil volumes. Medium angle sums should be used when speed and rev rate matches."

Well, the center I bowl in is oiled 35-37 feet, medium oil. I usually bowl first shift, so carry down and burnt heads are not so much of an issue. I have 10-12 degrees of tilt (~11.75 track dia.), and I'm slightly speed dominant (15.25 at 40', 225-250 rpms).

The oil pattern and low axis tilt suggest a larger angle sum, but speed dominant players should use lower angle sums.

OK. So I took a look at the Drilling Angle, and Angle to VAL suggestions.

For the Drilling Angle, small angles roll soonest (10 deg.), large angles roll latest (90 deg.). I was thinking with a high Rg ball, I would want a slightly later roll (50-60 degrees?).

For the Track Flare, I want a strong ball so I was looking at 4-5 inches.

For the Angle to the VAL, larger angles (70 deg. max.) promote a later, sharper breakpoint. Smaller angles (20 deg. min.) are less angular, and sooner. Since I have some smoother, more arcing solids, I want a snappy ball. I was thinking 50-60 degrees again.

This leads me to a ball layout of approx. 55 x 4.5 x 55. It adds up to 110 degrees.

Given my speed dominance, will this ball still be snappy? I was originally thinking my angle sum should be less than 90?!

I haven't laid out a ball in almost 5 years, so I'm trying to refresh myself on this technique.

Thanks in advance for your help and advice.

The larger the angle to the VAL the smoother the ball will be. So for a snappy angular reaction you want a 10-20 degree angle

Here's a good guide to laying out dual angles:

Sorry Guys. You're right! I think I misread the paragraph.

Page 12 (again) says "Larger drilling angles in relation to the angle to the VAL will create larger, sharper breakpoints (more backend). Smaller drilling angles in relation to the angle to the VAL will create a sooner, heavier roll (more midlane)."

Back on Page 6, "using the minimum 20 degree angle will result in the drilled ball revving up the quickest and transitioning the fastest at the breakpoint."

I assumed that page 12 was a summary - and it is - but by not reading carefully enough, I misinterpreted it.

Now I'm looking at 50 x 4.5 x 30. Total angle = 80 degrees. Sound better?

I made that same mistake when I first read it too.
