People on this spreadsheet are recommending anywhere from 3% to 10% https://spreadsheets.google.com/spr..._hQ6Fu8HdEwwR2dLRUJlVjlabEN1NG1ucktuUVE&gid=0
I'd start low with this one.
If it's of any interest i buy a forest fruits concentrate from Ebay which is pretty good.
30ml 50ml 200ml 500ml EXTRA CONCENTRATED FLAVOURINGS FOR E LIQUIDS 153 FLAVOURS | eBay
30ml is only 3 quid, but it's not particularly strong stuff, need to mix around 20%
They do a nice Skittles concentrate also, i'm likely to buy more stuff from them in the future when something else tickles my fancy.
I tried their sherbet lemon and it was tasteless even at 30%, maybe other flavours are better, perhaps you could recommend some of the other flavours you have tried?
Only those 2 so far, Forest Fruits and Skittles.
Both need around 20%
What type of atty do you use? perhaps some are better with rta or rda`s as I tried the sherbet lemon in a protank and it was pretty poor.
I use a Heron which is pretty much one of the top atties for flavour.
Is a protank one of those kanger thingies? I remember when i used a kanger T3S and the flavour was poor compared to rebuildables.
