Not saying you won't get lucky, but as relatively cheap as they are, and with no additional work, it just seems wise to me to go ahead and replace the slave cylinder when doing the MC. They are really annoying when they decide to not hold pressure, and that can occur in the worst, most remote conditions. Or on the way to work. Just not worth it IMHO.
