These grips stole me away from the ESIs I love so much. I've used Troy Lees, Lizard Skins, ODIs, and these Easton's are the perfect balance of width, stickiness, and grip pattern. They're easy to install (locks on the bar end and on the stem stem side) and even look good.
I bought one pair for my 575, hammered out a 20 mile ride here in Park City, and then immediately bought another for my DB Mason. Highly recommended.
