Well, aside from comfort issues, it increases the influence of your middle finger, and can change the way you throw the ball slightly.  But in your case, I'd say comfort and a better fit is what the deal is. 

I went to a Sarge Easter grip for about a year.  One thing I noticed is that it brought my track up higher (closer to fingers) which produced slightly less back end reaction but stronger roll.

I remember Robert Strickland from his days in DFW area, now that you mention it I was told years ago that I needed 1/16 offset but at that time not many drillers believe in it, they say numbers or just numbers. I also remember my team captain in a match point league would let me use one his ball, he had 1/8 off-set it felt really good I may try it again just to see how it feels.

Most (not all) bowlers have a shorter span in the ring finger.

I have to disagree with this statement.  I measure on a Jayhawk-style (AMF version) measuring ball and set spans at the center of the distance between the first and second finger joints.  At least 80% of my customers have longer RF spans than MF spans.  --  JohnP

In the Bill Taylor book Fitting and Drilling a bowling ball, he mentions about the RF span being longer.

"When the first joint lines are in alignment the actual span difference, on the ball, should be 5/16ths inches longer on the ring finger................................When the ring finger line is 5/16ths below the center finger line, the difference on the ball should be zero"

or said this way

"Most peoples middle finger "span" is shorter than the ring finger span! Even though the middle finger is longer. The breakeven point is when the middle finger is 5/16” longer than the ring finger according to Bill Taylor."

Another thing I seen about the ring finger span usually being longer It was

"Because of the distance from your thumb to your ring finger, is greater than the distance from the middle finger to the thumb.

Just look at the palm of your hand, your thumb is farther away from your ring finger. Than it is from the middle finger. "

Just because a person's ring finger span is too long does not necessarily mean the ring finger span should be shorter than the middle finger.  The reason a lot of people have ring finger spans too long is it is very easy to measure that finger too long when using a BT Fitter.  You can't lay the hand out on the edge of the fitter with the ring finger like you can with the middle finger.  If you do the span ends up too long. 

The only problem with the 5/16ths rule is it doesn't take the shape of the hand into consideration.  There will be a big difference between a guy with a wide hand and a thumb that looks like it comes out of the side of his hand and a lady with a narrow hand and a thumb that looks like it come out of the middle of her palm.

The vast majority of ring finger spans are longer than the middle finger spans, though not significantly.  I always remeasure anytime I come up with a fit where the ring is more than 1/8th longer than the middle finger, but it also depends greatly on thumb position and thumb pitch.  You'd have to put the thumb out of position to the right (righty) or have a lot of right pitch to get the ring shorter a majority of the time.  I'll look into the Robert Strickland book just to see what's up, but the most common fit I've seen has the ring 1/16th longer than the middle. 

I dropped my ring finger and my 1st line of oil moved down 11/2 inch
