Putt alignment | Golf Monthly
Might be slightly different to your question but when I first started I used a plain blade type putter with a straight shaft and found sighting and aiming awkward. I have since bought two old putters off the bay and cleaned them up and put new grips on. Ping Bergen and an Odysey Rossie 2. They both have double bent shafts so the putter head is kicked off to the side. My putting has changed massively overnight using these styles and I feel much more able to sight and shoot accurately. I sight standing upright.
I don't know what type you are using but could you borrow a couple of putter styles and see if they are easier to sight from a standing position.
Hope you repair soon.
