I have been using them for a few years on all my clubs and they are great. I do have bigger hands so I don't have to grip as hard. I just had to replace my 1st gen grip on my driver because I wore it out. I don't know about distance or accuracy as I'm a weekend warrior and struggle with both on a regular basis. (I'm 61) If you are in doubt, just try one to start with. I would suggest small and go from there as far as the sizes go, unless you have really big hands.
