i just wanted to know if anyone can tell me the advantages or diss-advarntages of using a rapid rise mech. I have never used one before. But have just obtained one. Im building an all xtr set-up and now have in my possesion an m952 normal and an m953 rapid rise. So i dont know what to use. Both are long cage. Also is setting a rapid rise up as easy as a normal mech?
