Middle of the left hand - for me it’s about tracing the target line with the right forearm now. Moving the putter more in the left palm helped keep the left wrist from bending. Any braking down of the left wrist takes the right forearm and putter off the target line.

For a while, I putted very consistently with the straight left wrist - more of a left arm putt. Now, I have moved my focus to the right forearm staying on plane or tracing the plane line, since my left wrist now stays straight/flat. By adding the right forearm, the ball rolls with more authority towards the hole and holds its line better.

I’m not an expert – just sharing my experience.
