In my opinion no. Having something a hair bulkier to strip (and do quasi mends) with outweighs the extra distance. That's just me though - I might swing part of a run and strip it here and there, then again at the dangle. I might just strip it the whole way in.
I spent the day fishing my 4wt SR with a 275 head and mono runner. The mono drives me crazy. I've got another rod that I run an Ambush on and I dig it. I think I get pretty good distance out of it too, truth be told.
