Finding my favorites juices has been the most time consuming for me, too! I keep ordering sample packs from everywhere and so far have found one that I LOVE!!! Still searching for more.
First juice I purchased was from Volcano. DO NOT WANT. Not sure why I disliked it so, but not again. I tried two flavors (peach and tobacco) and was just not working for me. Came to realize that heavy PG juices are not for me.
Moved to Johnson Creek because they have a 100% VG line. Tried Island, one of their tobacco's, and Marcado. I enjoyed all three but the tanked cartos I was using at the time performed miserably. Not sure if the juice caused this though.
Currently trying 8 new sample flavors from Desert Vapes here in AZ. Gentlemen that owns the place was nice enough to let me come pick them up even though he has no brick and mortar.
At this moment I have two VVN's running. One with Wild Cherry and one with Spearmint. They're both okay. I will be ordering larger bottles of a few of the flavors I've tried from DV, but will make use of his made-to-order feature. Going full VG to see what happens.
