I'm playing a YES Stephanie Mid (400g) cut down to 32'' with a SuperStroke Slim 2.0 (64g) and a 75g counterweight. I struggled last year with a shaky stroke and this combo has really smoothed it out. It feels heavy, but the counterweight seems to add a nice balance. I haven't putted this well in years.
These grips are not a marketing stunt. 'Reminder' or 'Ribbed' grips have been around forever. Many pros play them. Used to have to special order them. I just put the Tour Velvet version on and love them. Nice subtle feel in the fingers. A little pricey though at $9.
