I'm a guy that has struggled with putting always. My lags were ok (never have to be too precise with them as far as the line), but 3-10' range was terrible...yet somehow I still maintained a 4-5 handicap.
These Cures are game changing. I have an Rx2 and swear I will never change. The high MOI does what it says and is very easy to roll the ball on line (even with a less than stellar stroke)
The adjustability is what's incredible...
My putting stroke WAS a normal grip (RH low). So lie angle was set at like 69-70°, but I noticed I'd still get too active w right hand and pull or push slightly. I threw an older (heavier) superstroke belly putter grip on it and went with the claw grip. WOW!!! All I did was make it a lil lighter, since I'm now only really gripping w one hand. And I mad the lie angle 73°...two easy adjustments that made a world of difference.
They may look ugly, but if you've ever struggled with putting, do yourself a favor and take a look at these.
Feel free to hit me up with any questions. I have a bunch if anyone wants to try em.
