As I said earlier, I have used a bullseye for many years. Last fall I bought a used SC Fastback 1 and put it into play this year. After trying for six months to learn the Fastback, I have gone back to my Bullseye. My putting stats have dropped over three strokes a round since I switched back. Of course, my Bullseye is an Acushnet product, not a Titleist or SC, since I bought it in 1968 or early 1969. Just feels right on the greens, especially fast greens. The only change I've made to it is to change grips front he original leather wrap to a Winn Jumbo LIte.
