I have a HS11 and i think its rather good to be honest. I dont see much point getting the HS33 2011 cause its exactly the same but then the only down side is the lever body is plastic so the threads may go on the bar clam but other than that its a pretty good brake but over sized haha. I doesnt feel much different to the hs33 05 but i would go for an 05 if i were you
you can get a 4 finger for the HS33 on chain reactions and its cheaper there
