I’ve got the supercaz version of the ESI’s. I used to like chunky grips (I’ve got XL-XXL hands) but since moving to silicone grips found that the chunky (which is still probably narrower than a Yeti lock on) is much more comfortable.
Some brands get slippier than others in the wet. I’ve had some ebay specials (£1.20 a set!) which have been great all the time, and others were a bit rubbish. Supercaz seem fine, although are wearing quicker than my old ESI’s. But that might just be because they’re a light colour so show up the nicks and scuffs more than my black ESI’s.
