Brat seat length? 1992 Nighthawk CB750

I have a 92 Nighthawk and I’m trying to wrap my head along how to finish this rear hoop. I have tons of photos and ideas.I think 24” is the minimum I should be looking for, but the problem is frame swoops up in the rear and I’m worried that it’s going to look funky. I’m in one of those “will i regret whatever I choose” situations. via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/ehwjby/brat_seat_length_1992_nighthawk_cb750/?utm_source=ifttt
