Good morning and welcome to IIS!
That's a nice optic you have there, I use one occasionally and it always pleases. Sharp, forgiving and portable. However, eyepieces being the interface with the observer are the second-most subjective thing after the observer themselves. Expect to find lots of info, and not all of it consistent. I'm lucky in that I have access to a range of good eyepieces, and the best ones for the 6" f/8
for me have been:
The 32mm Televue Plossl
The 24mm Explore Scientific 68°
The 16mm Explore Scientific 68°
The 9mm Astro Hutech Abbe Ortho
The 6mm Fujiyama Abbe Ortho
Astro Hutech and Fujiyama brands are interchangeable for all intents and purposes.
But, in response to your question, a Superview should also work well given the relaxed focal ratio. Use above focal lengths as a guide when selecting. Perhaps start with the 16mm and 6mm brackets a mm here or there won't matter all that much.
Filter wise, a UHC is nice but OIII I find slightly more useful when there's a need for filtering.
Adapting the scope I use to 2" is a pain, so I haven't actually used any 2" eyepieces with this telescope.
