The reason for so many putter designs, grip sizes, and ways to stroke is putting is such an art that what works is what works. May not work for anyone else. I was fit for a Newport 2 in LH for the toe flow. I had difficulty with alignment - the one reason I have used mallet styles in the past. I'm not a fan of the limited LH options from not only Cameron but others, as well. I tried other putters, but once you've used a Cameron, everything else feels wrong. In desperation, I got a RH X5W RH putter. Set the weights to 15 Heel/25 Toe for toe flow. Not sure that L eye dominant should putt better putting RH, but I see lines better and I'm not fighting the putter to keep it on line through the stroke. After 3 putting the first 2 holes, I had 1 more 3 putt, 5 - 1 putts and 10 2 putts for the remaining 16 holes. That's on my first round since November and my first round putting RH in 25 years. This was on Torrey Pines North which is not mostly flat greens. So I'm now at peace with the Cameron lines limiting the number of LH putters.
