For putting i have both thumbs straight down the middle of the grip but have my right index finger pointing out towards the bottom of the grip which personally enables me to control my distance better.
I was tempted to post "I doubt it," but I have this blog to use, so I'll use it for a quick discussion of this.
I've taught a few thousand people to putt. I've never seen someone with their finger down the shaft who I would consider a "good" putter. More often - far, far more often - those with their finger down the shaft have distance control issues. The pressure they apply with that finger leads to added loft and wrist flipping, while many good putting strokes have de-lofted putters (4° turned down to 1°) and lead wrists that are slightly more in flexion than they were at setup.
I understand what people think they're feeling - the pressure of the shaft/grip being applied to that finger - but again I've got SAM data and visual data (recorded) that leads me to these types of statements.
I'm not super picky about putting grips. I putt with a pretty standard/classic reverse double overlap. My daughter is a single overlap kinda gal. I've taught claw grippers, crosshanders, etc. I could put the finger down the shaft (at least for awhile), and remain a good putter… but part of the reason I might be a good putter is that I don't put the finger down the shaft, and I've learned to control the putter swing by having a better wrist action than the one that the finger down the shaft encourages.
Again, I've never seen a good putter who can actually control distance well with the finger down the shaft.
Take it for what it's worth.
P.S. If you try to putt without the finger down the shaft for awhile, don't judge the results immediately. Give it some time. And read this:
P.P.S. Just because I've never seen it doesn't mean it doesn't exist. It only means I've never seen it…
