I've updated the design. 

Aesthetics

- Turned the rectangular cut-out into a half-moon

- Removed the lettering and left the logo

Practical

- Cut the putter width from 1.5 inches (I think) to 1 inch to cut weight from the design

- Added 3° of loft to the front of the putter, up from 0°

In the first image, there is a blue line coming from the center of the putter. According to the in-program CG function, (thank you for the idea @boogielicious and thank you to @saevel25 for pointing out the CG issue), the CG is in the direct center of the head. 

Cutting that half inch of solid weight made it very easy to get the putter head into normal limits. It sits at 296 grams on its own, which is a little light, but with the shaft and grip I plan on putting on it, it'll be right where I want it. 

As I said before, I'm on a good path.
