differential values

Post by turbotwister »

i can't seem to find a chart showing the differential values from lower to higher?

I don't know what chart you are looking for. Are you talking Total Differential or Intermediate Differential for example.
They change a lot with a drilled ball. Here is an example I just looked at from the Radical Home Page when I was looking at their newest release: (just click on suggested layouts on each ball and Radical gives you their differentials based on a generic span and finger and thumb depths and sizes I think).

http://radicalbowling.com/uploads/downl ... ctions.pdf" onclick="window.open(this.href);return false;

You will notice that the Intermediate Diff. varies from .040 to .075 while the Total Diff. vartied between .020 and .050 using these basic layouts.

Edit: another example The Fix
I.D. from .006 to .032
T.D. from .039 to .072s

If you mean a chart of balls sorted by Diff., You can go to bowling this month's ball comparison table. Then just click on the Diff. button and it will sort them by diff.

Other than that there really isn't one.

this is a part of the article that i was reading and i thought there might be a scale to go by ( say like .000 to .057 or higher)? my friend said that he goes by the RG and the DIFF and that's what i'm trying to find more information about this subject.

The diff. ratio is also an indicator of how quickly the ball will respond to friction. The higher the value, the faster the response to friction. This is the reason why Asymmetric cores tend to produce more angular break points than Symmetric cores.

i guess it would be similar to an RG scale....say from 2.46 (early hook) on up to over 2.80 (more length/later hook) but in a DIFF scale?

Those are fallacies. The legal undrilled ball scale for RG Differential is 0.000 to 0.060.

Your talking about this old scale:

The RG Differential aka:The Differential:
Shows the difference between the low RG and the high RG.
The Differential indicates the potential for track flare.
The lower the differential the closer together the track flare rings are.
The higher the differential the further apart the track flare rings are.

Simple Differential scale (there are others):
Low Diff.-RG: .01 - .02 (low flare potential)
Med. Diff.-RG: .021 - .04 (med flare Potential)
High Diff.-RG: .041 - .06 (old .08) (high flare potential)

Note: As megamav pointed out they have since change the limit on Diff. from 0.080 it's now 0.060

i guess elgavachon is right also,saying that it changes when you drill your ball. even when the ball is sanded or polished also changes everything too. i guess the numbers are a good starting point if your buying a ball though. there's more to this than i realized and not enough time to get it right..lol
