Not 3x3 PB Ao5 (only 3rd best) but I think this is my 1st counting sub-15 in an Ao5 so...

A bit lucky with the PLL skip but the other 14.xx was a full-step and it could easily have been sub-14 (and new full-step PB), as I was a bit sloppy on LL.
Also, it would have been by far my PB Ao5 and most probably my 1st sub-17 if it wasn't because of the stupid 25 and 21 in the middle. If just one of them had been a very "normal" (for me) low 19 or high 18...
Oh, I almost forget, I said back then when I tried it that I hated the Yuxin. Well, this Ao5 was done with it and I don't hate it any more. I didn't try it again because of Collin Burns' WR, I did it just because I kept watching good reviews and decided to give it a 2nd chance. I am less consistent with it than with my beloved Chilong but, who knows, with some adaptation in my turning style it could be my new main

I don't even have my custom sticker shades on it yet, which will surely help a bit with recongnition and lookahead.
