Both the Natural-Fit and the Natural-Fit LT come with Standard Grip or Super Grip coating options for the thumb piece. The Standard Grip uses a powder coat on the thumb piece that provides a low friction surface to go along with the smooth braking surface on the oval. For those users interested in the ergonomic features of the Natural-Fit but who do not like high friction surfaces, then the standard grip may be your best choice. For users who want both the ergonomic benefits of the Natural-Fit along with a grippier propulsion surface, the Super Grip will be the better choice.
