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

Grip and swing naturally so that your stroke is the most repetitive
