I pound out commutes on the R6 in Baltimore/DC metro traffic- as far as holding the clutch compares between the RC2 and OEM levers, its about the same. Lots easier to get the right grip and lever distance with the CRG's. OTOH for real shortie levers are probably a different thing entirely.
I’ve always used ASV levers. They are pricey but strong, look nice, and ASV will customize them to your liking. I’m using their C5 levers with gold adjusters with my R6. Adds a little more gold accent to my bike without looking gaudy.
