Like about anything else, it will be all about putting in the time and getting comfortable using it. Too many people try something a handful of times and, if they don’t see instant gratification, they revert back to their old stuff or move on to something else new.
Heck, I moved from a standard size pistol grip that I have been using forever to an extremely heavy and big Two Thumb rubber putter grip to help control excessive face rotation during my stroke. I also changed my putting grip from conventional to prayer style. It took a while to get used to it but it has achieved the desired results. FWIW, I have tried SS grips in the past and just do not like the polyurethane wrap on those type of grips. That is why I went with the very heavy rubber jumbo grips and got adjusted to losing 20 swing weight points.
