Weapon Progression for TH

Heya guys, I'm curious about what weapon progression works best for TH. Right now, I assume that focus > all, so it looks to me like:

C: Dark Screamer or Grace Dagger
B: Kris
A: Bloody Orchid

Has anyone run a different setup that has worked well for them? I know SA crystals are hard to get for A-grade, so is there another dagger that would work well without an SA or should a TH save up for the crystal?

replace BO dagger w/ OE'd kris (+7 or so should be like 60-65m same as orchid/focus except consumes way cheaper bss and has more critical)

kris+3/focus is way better than BO/no SA
{i am a TH using OE'd kris, it's wonderful)
