My Ls leader insists that all THFs fulltime TH+1 gear. A lot shells are like this.
Your shell is stupid.
This. It doesn't matter what you wear when you first attack a mob on THF....it's not like they're checking, "Oh, this THF didn't wear his armlets EVERY time he hit me, NULL & VOID!!" I theorize that it only matters that you wear all your TH+ gear together at some point and perform an action on the mob (no proof, no evidence, just theory), but to be safe, I always macro in all my TH+ gear the last time I act on the mob. But what you wear for 90% of the fight shouldn't matter as long as you put the TH+ on in the end, and any LS who insists on fulltiming TH+ gear is just...silly.
