After you spend a lot of time building 1/10 scale shocks with a bladder and then try emulsion I don't think you can go back. Much easier to repeat results and get a pair of shocks to be the same. Takes some practice to do it with bladder. Emulsion is so much easier. For 1/8 scale I still use bladder, but plan to make the jump to emulsion soon and I will not be going back. JMHO
