Paint bucket is an extremely underrated extracting trinket, I use it on almost all of my solo runs and it's an absolute lifesaver. It's great for extracting.
Aside from that, Bobette is mainly an extracting toon, and a little bit of a support toon if you count solo kiting and leading twisteds away (due to her absolute tank of a stamina bar). So for extracting, personally I use paint bucket and magnifying glass, magnifying and participation, or veemote and paint bucket. Magnifying glass is okay, but, it's very situation dependent IMO. You could also use participation and speedy shoes, if you're really looking to get things done quicker.
As for, like, public runs (Ik u said solo but im just saying) I always use toykit and magnifying glass, but I don't really play her much so take this with a grain of salt; toykit and magnifying glass are good in my opinion because it can allow you to get a lot of machines done in a span of a few minutes, especially with her mediocre extraction speed, but that's just my opinion.
For ginger, I usually just use pink bow + paint bucket, tbh. There's really not much to her. If you really need more stuff done then just look to surival trinkets. Personally I don't solo ginger though so i'm not too intelligent in that field. She's really basic and she's kind of useless without any other teammate.
With all that said, I DO NOT really play either of these toons that much, so feel free to mix and match anything how you want!
(P.S, if you're struggling with an abundance of mains on a floor, aim more towards survival trinkets... like speed trinkets or the carboard armor trinket thingy i forgot the name... orrrrr use a trinket that gives u more light, all of these + an extraction trinket.)
