Quite a few other professional use larger sized grips on their equipment.
Rory McIlroy uses large grips on at lease the shorter golf clubs. Of course Bubba Watson uses extra large built up grips.
I noticed from the archive, even Ben Hogan used jumbo grips later on in his career.
The built up, extra jumbo grips will allow the golfers a swing style between golf swing and baseball swing. In my opinion, it's easier to use larger grip when producing high club head speed, One need to have very strong wrists / arms to properly execute the set and release of the golf action when using extra large golf grips.
It's not for the weekend golfers.
Please review the smaller sized grips on your second set of clubs. I suspect the results will not be as consistent as the jumbo sized grips. You might even lose some distance with the smaller sized grips.
