Hello! Sadly i have to switch to the new style HS33 lever during the next couple of weeks because my 04' is leaking. What are your experiences with such blades (not including lever bodies) from Gu, Adamant, etc. ? Are they worth it? Should i wait for the 09' ones - will they be different?. Or what about the 4-finger HS33 blades? thank you! didn't really get some answers with the search function
