"The NO1 50 Pro black on black (they just recently added color options) grips has a very clean look on the club and offers a unique feel and tack. They are soft and firm at the same time which really is spectacular. They may set you back a little more than a standard grip, but you actually get something for you money which is noticeably different in a good way. According to NO1, The NO1 50 Pro grip is a new proprietary elastomer compound which features a more firmer and solid feel while maintaining the signature sticky and tacky touch of the 50 series. So these are not your standard rubber grip. The elastomer compound is much ""gooier"" than a standard rubber. It has a real flexible feel to it when installing the grip. I did an air install like I do with all my grips and found them fairly easy to work with and once in position hold their position very well with out grip tape or solvent. "
