With the bullseye I find I was lining up nearer the hosel where the sweet spot is
Bulls Eye putters the best? - Page 3
Golf Gear mentioned in this thread:
I recently picked up two Bullseye style putters. One is a brass clone, an the other is a Bullseye by Titleist Scotty Cameron Platinum Blade. I got them both from a bargain bin for $5 each. Unfortunately, the Scotty has been cut down to about 32" and has a medium size PING grip. However after using it a bit, I have reconsidered my usual putter length and if I have it reshafted, I may go shorter than my usual 35". If we really fall in love, I may send it back to the Scotty Custom Shop for the refurb.
