With boys in the 60s it's going to be very hard to run f50 reliably. Think of it this way - f50 is a slightly kinder version of 7-1, the opening level of the current hardest era. It's not meant for newbies to run comfortably. Hell, I had a Nihongou I was using the event to grind up at around the same level and had to take him out of the party for f50 because he was too fragile even to just come along for the ride with my higher level swords. When you're only 20 days into the game, some of the content isn't really going to be free or easy to you, and it's not meant to be - I'd advise you to grind for some of the other event tantou on the lower floors rather than fixating on Mouri. You can get steadier drops on floors you can consistently run, and the f50 drop rate for all the event tantou seems to be pretty bad.

If you really want to go for it, oodachi and high level uchis are the way to go. Naginatas sufficiently leveled are good for most of a UTC, but to be honest at the ending levels they won't be able to peel off troops and thus kill the enemies. Even a lv99 Iwatooshi has trouble at the bottom of UTC, and he's expensive to repair on top of that. You want the oodachi for damage and spread, and the uchis are because you should have at least some long range. (I'd say use one catapult and one shieldman on each uchi.) If you have a kiwame at this point, toss them in too, but it sounds like you probably don't with your best party averaging 60 at the moment.

Also, do your best to maintain sakura fubuki status on your digging team if you do f50. It'll be tedious and annoying to grind it back up every few runs but it'll give you the best shot of finishing the level.

Good luck!
