well after my last post and all the answers i got i would like to thank everyone for all thier feed back and advice.So ive decided on the provari and im going to use it with the 510 slotted carto (SR) and the 3 ml liquidnator tank for my primary flavor, and ill get some boge 510 blanks for the flavors i wont use as much.Just wondering how many refills the vapes are getting out of boge 510 (SR),just so ive got an idea of how many blanks ill need for 3 months worth.Now for my last question what is everyone thats mixing thier own juice,are you using using vg,pg,or pg400 or a combonation.Tnx agian all much appreciated

total cost including postage to australia 280$ not including my juices
Good decision on the provari. It will not fail u (except for technical errors on provape side lol)
I'm using a CE2 tank on my provari which that 1 CE2 last me 1 n a half months in and still going strong. Only washed it bi-weekly. for 3 months worth of boge i'll recommend say 10-12 (assuming u change it once every 2 weeks and some can be washed and reused plus it nvr hurts to have extra on hands and in case of duds and also not too much in case u decide to try out other cartos and find those more suitable for u)
Juice wise, i'm on 60pg/40vg or 50pg/50vg mix depending on juice. I like my vape smooth and lots of vapor without too much th as i was previously a menthol light smoker and i can't stand reds. (next chill menthol is the brand).
Vape on!

As a reminder again, PG carries flavor and th better but thin vapor. VG gives thick and denser vapor and taste slightly sweet but dun carry flavor and th as good as pg. PEG/PG400 carries lesser flavor n th than PG but better than VG and produces thin vapor as well. It is recommended to use PEG only if you are intolerant to PG.
Nice damage, but keep in mind that u have skipped all of the small pv which builts up in cost so all in all, u have spent lesser than most of us haha~
Next improvement u might wanna get is, casing to protect ur provari from bumps and scratches whilst on the road and stuff. I have no recommendation so far but am using a XL eGo casing.
