Bridgestone has been working on revising their putting lineup with a big name for quite some time now. Last year at the Bridgestone Open practice day last year, many big name putter makers brought in over 100 prototypes for testing by pros that day. As you can see in the bottom left picture, there are all shapes and sizes and styles but it hasn't been revealed yet which are actually going into production (if any at all) :). Yusaku Miyazato was actually the main tester for Bridgestone back at that time. Remember these are still prototypes and could be tweaked if they went retail.

Dang... I need to learn to read Japanese

great post

I wonder when they are going to release the new line up?

The 16-21 Proto above is in play at the Sony Open right now with Yusaku Miyzato... no official word on when and if which putters will come out...
