Norco Sight: ESI Grips

In the 2015 season I will try to use ESI Chunky silicone grips on my Norco Sight trail bike. They say that these grips are very comfortable.
I've installed ESI Chunky Black with the help of Vodka and they look very nice on my bike. Even  Chunky grips are more fat than ordinary lock-on grips and this will be very good for my large palms. I can't even imagine how fat will Extra Chunky be?
