I have 5 mods and 5 tanks that I rotate..... I do like a variety during the week.
Normally a coffee type Vape in the morning
A fruit juice during the day which is rotated day by day
A desert juice during the evening which is also rotated day by day
Keeps me happy
Ive mostly just been running my Atlantis and Nautilus lately, I vape mostly fruity flavors, so swapping out flavors is quite easy, very little cross over. I also have a few old iclear30s and iclear30b, sometimes I will stick a flavor in there, but running low on coils for them so they will be retired soon.
More importantly, you have an awesome LAMY fountain pen in your picture!!
I use about 14 tanks and 9 mods, clean the tank out when empty, change the cotton / coils if needed.
