Picked up the extrema grips to replace the well-worn factory plastic. Noticed IMMEDIATE improvement in tactile feel and also slightly slimmed up grip for my medium sized hands. Definitely love the looks/feel -- only downside is they do seem pretty pricey. That being said, doubt I'll ever wear them out.
Pros: Ergonomics -- greatly improved grip
