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.
