I have two new putters with me now. 

Brand: Yes! C-Groove Callie Putter (Paid approx. $92)

Brand: Titleist Scotty Cameron Studio Style 2 (Paid approx $215)

These two putters look and feel almost identical in design.  I have not used them on the course yet, as I live in the North East and currently is winter.  I have only practiced with them on putting range, so this is not a true on-course experience.

Placed side by side they are identical at address!!  The both feel & react similarly, at least when at an indoor putting range.  I plan on keeping both putters for the true on-course test; once I have more feedback I will update this guide.

Side by side comparison, they look and feel very similar.  The Yes! putter cost less than half the Titleist Scotty Cameron.
