I grew loofhas this year and has success. But my question is...I have some very large loofahs that seem to just get bigger and then I have some that (to me) are small and are turning yellow. I can't find a good answer as to know when to pick them. Any advise? I can't let them dry on vine because it's getting down in the mid 30's already

You could, with two caveats: they take forever to mature (like 200+ days), and they take a lot of space (like 6-9 meters). So I think it's too late for you to grow them outside this year, but you could still grow them in a LARGE greenhouse...they set fruit during short days so time your lighting accordingly. Your best bet is probably to start them indoors in peat-type pots in late winter for next year.
