Phillip,

With a very slight putter arc, a Scotty Cameron with near minimum or minimum toe flow would probably be best for you.  As with all clubs though, you should seek out the advice of a certified Titleist fitter to find the putter that best fits you.  The following link may also be helpful when looking at all the putters offered by Scotty Cameron.

Best of luck with finding the right putter!

Fly to SD and get a fitting at the Scotty Gallery, it's top notch.

I agree with Barry, a little toe flow will work well...examples would be like a plumbers neck putter such as Newport or Newport 2.

As others have mentioned, I would recommend the Newport, or Newport 2 also.  If you are unsure or want an a more precise fit, you could get fitted with the help of a professional.  Good luck!

Check out the "Detour" , the alignment line has a slight curve to it. I own one and it rocks.

Phillip, what did you choose?
