Four times a year my Golf League plays across the street at a harder course (138 vs 123 slope) and where the greens are much quicker with more undulation. I have to say they also seem to roll much smoother. Today ended up with my best putting in awhile with my HB Soft Milled 10.5c. Finished with 29 putts that was almost 28 after 1 50 ft birdie putt made a right turn in front of hole and stopped. Seven one putts and no 3 putts. Just love the feel and sound of this putter!
