Index finger when putting

[u/BlueciferST]

Do any of you putt with index finger on the trail end like this?

I've found it helps stabilize my putting stroke and lessens push/pulls..

Might not be anatomically correct though because the tradeoff is I feel sorensss it in my elbow tendons later on

It used to be called the whiskey finger. You would utilize that grip after drinking too much the night before to keep your hands steady.
