It sure didn't work for Adam Scott this week...

I've used a "Sternum Putter" messing around at the shop, but never one that goes in the gut like Freddy C.

The best quality and easiest way to paint fill wedges is to buy a paint pen from your local hobby store (Walmart works) and basically color in the areas you wish to change and then wipe off the excess with nail polish remover.

I hit the D3 farther.  I was originally playing the 907D1 (460 CC) and figured I would lose distance.  The cary distance was just a touch longer with the 910 D3, but the total distance was better.  You can't really go wrong with either one.
