hey guys..i'm wondering what thread cover would do the best on the mini vivi..I have an 18650 tub mod coming in if that matters on the style of thread cover that would do best.. i'm thinking style C would flare too much and is for the larger vivi..style D looks like the right one? it looks like it flares a tiny bit right? or would the straight be B style be better? thanks in advance! edit: did some digging and searching and found type D is for mini vivi nova's and type C is for the larger vivi..in case someone else searches for this topic and finds this thread..cheers..
