Now your talking! Can you use the 9mm plossl without glasses?
If yes then anything is usable. I don't have astigmatism in my eyes but I believe it only shows up in longer FL eyepieces for those who do. I guess your dob doesn't have tracking so 70º+ eyepieces are probably the go….can be expensive though. Pentax XW's barlow well so get the XW 10 and 7 + a 2X barlow to give 5 and 3.5. Meade HD5000 60º eyepieces are pretty good too, cheaper than XW/Delos, with 17mm ER worth a look. As my scope has tracking I get away with narrow FOV Ortho eyepieces.
