I have a few bucks to spend on a new filter and would like some recommendations. I'm using an unmodded Canon 600D, William Optics ZenithStar 80mm, and I live in horrible Bortle 8 Las Vegas skies. I have an Optolong UHC filter (clip in). Would I be better off getting an IDAS v4, OIII, or some other variety of filter? What would serve me best for shooting nebulas under my conditions? Thanks.

I've read a lot material but not that one. I will, thanks.

On the long term a mono camera and a set of Ha, O3 and S2 filters. Easier to use but less versatile an OSC astro camera and the Optolong L-extreme. If you want to continue using a DSLR I'd try to get a modded one with a more recent less noisy sensor like the 800D. If you want to keep the cost low modify your 600D first and try the filter you have. From measurement I made in an optics lab I'd say modding a 600D doubles the Ha sensitivity. That is not really a lot, just one f-stop. Given the low QE really think about a mono camera with a Sony backside illuminated sensor.
May I ask how much "a few bucks" is? Enough for a mono camera or enough for a mod?
