not sure if this has been mentioned anyway, Adam (Punkrider) has an RB Lever Blade in his magura body, looks good and i don't think it even leaks, works aswell as it being in the rb lever body. You could go for that.
I have a whole Rb lever and an rb lever body, i'm just going too try out the wholoe rb lever first and see how much it leaks....entirerly up too you mate
:(
EDIT: and NO they are defoantly not worth £60!!! :(
