I did come across this article a few days ago, it's interesting reading on filters. It's written by David Knisley. Though the review only mentions the studies were done on apertures of 8" and up (so I don't know where I stand), but it makes note of exit pupil. It also lists which nebulas perform best for each filter. You guys will make more sense out of this article than I will as you'll are more experienced in this field.

Hello Suzy,
A UHC filter is better than nothing. At a dark site a UHC would be the preferred filter, at a light polluted site an OIII filter is the way to go due to increased contrast.
Ultimately it depends on where you observe. Can you see the SMC from your site?
Regards
Steven
