different strokes for different folks........ here's what I do.....
I have my main flavour for 70% of the time....... mild
tobacco... keep this in a pt II
my 'need a change' flavour for 20% of the time..... wild cherry... keep this in a pt II also
the other 10% of the time, when I want to experiment, I use cartos.... I keep one beside each bottle of different flavour.......
and that's how I do it
