Yes, I had one a few years ago and was fitted for what i have always used , a face balanced putter .
The brand, SeeMore, a great concept for alignment. I already had a SeeMore and believed in the system.
the one thing i did not like or made me question the process, was the distance was approx 12 feet and very fast. So a very short stroke was involved. Different putters did confirm the SeeMore was the fit.
So I stayed with a SeeMore and face balanced. With a face balanced putter I found I have a tendency to take the putter back outside the line and pull putts.
Last winter I bought two inexpensive Ping blades I knew I could sell. One an Anser style and the other a Zing style. So moderate toe hang and extreme toe hang. After hundreds and hundreds of putts I decided I needed toe hang and alignment.
Last year I bought a TM Spider Tour Black with the T alignment, slant hosel, 33* toe hang, smaller grip and putted very, very well. I also went an inch longer to help promote an inside take away. (Figured can always grip down if needed). The horizontal line helps pick the line and the perpendicular line serves virtually the same purpose as the SeeMore, helps put the putter in the same spot every time and ensures the face is square to the target.
No more faced balanced.
