I tried several clubs from my set with Shaft tease. stung hands-on mishits. I tried the others without Shaft tease. ALL my clubs now have your product in them now. these work well! on solid hits all is good. on mis hits it is not something that would make you timid in case of another mis-hit if you get what I mean.
I am ordering more for a set I am regripping. Too bad you do not sell them in sets of 10 or 13
