The point Nic was making about using a personality (ie not a dimmer) is that the machine (specifically a hazer) could be used LTP. Dial in the value and leave it...hazer levels are unlikely to change throughout a show; plus you save one, probably two handles.
Obviously with a smoke machine, it needs to be on a handle for instant access. Just remember to clear it before programming chases (been there and done that

).

ps As it happens, I prefer dedicated remotes for both smoke and haze, I once had a desk go bonkers and filled a hall up with smoke, unfortunately it wasn't a rave, but a kids thing....
