Don't get me wrong, I love Li and his service, but as of late, I can't consider him the best any longer. Still amazing. But the dude has 5K customers he is trying to message each night and just has too many customers to maintain (in my opinion) - he could use more help as Lana just does packaging/shipping. Not to mention he doesn't work weekends now. I still use him but have been using other TDs with less clientele, and I get equally good service and faster speeds.
It might benefit you to reach out to multiple TDs when you want something. I have never been afraid to order the same piece from Multiple TDs, and when one gets me pics in 3 days, I cancel the order on the other TD that said it was going to take 14. They do so much business they will sell it to someone else or send it back to the factory. It's not a big deal.
I ordered a black Clean V3 dial for $150 from Eric to toss into my V2 BTF, and got QCs in about four days, and the coronet was fixed compared to the first batch. To me, that will make a perfect setup for the black. For the panda, I bought a creamy Noob v4 dial for $50 from Domi last week for my v2 BTF, and I think that will be the best setup for white (my opinion). BTF makes some killer pieces with excellent crystals. Toss in a dial, and you are mint.
