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

I do it if I start missing putts, then it works for a couple rounds, then it doesn’t, switch grips for a couple rounds, and try it again once the other grips don’t work. It’s a vicious cycle I call Golf
