My mixes are all baccy based though alltough I mix less in flavour than most,at only 5% or 6% flavour.
My first mix was 5% Kandi-head golden virginia.
Then 4% gv with 1% Kandi-hed cuban cigar
Then 3% gv 1%, Mom & pops ry04, .5% cuban cigar, .5% havana tobacco,
The last one is my current baccy base that I vape as is or add up to 1% of other flavours that take my fancy, mainly fruits or aniseed and I am sure I will continue to tinker with the flavours for a while yet.
I would recomend this method of building up a flavour you like,gradually getting better and more complex with each mix.
If you wanted to try something like my mix you would probably want to double the percentages.
