Welcome to the forums!!
If you avg 14-16 with cfop it could be a good idea to stick with it... but does the method feel right to you?? if not try roux and see if thats better...
again welcome
Cool, I got a Yuexiao too. Bought wt. 3 lube with it though...
If Roux doesn't work out there are also plenty of methods here on the forums .
