I don't seem to like the complex mixes in a dripper.. and Vanilla Custard is bloody vile.. not just my DIY, but Steamgunk, Grants & Goose Juice all taste terrible.. I use VG based Nic as well so thats not a problem..
I like my very cherry blend (5% FF Cherry & 5% FF Black Cherry, 90VG/10PG 3.2mg)
Loved straight up Raspberry 10% FF Raspberry (but run out)
Currently vaping Lemon/Lime Sherbet (5% VRS Lemon & Lime 5% FF Lime, 90VG/10PG 3.2mg)
Got some Pastry Island concentrates on route so will see when they arrive..
30% or 40% flavor in a Kayfun ad could hardly taste it... don't understand their hype..
I find the clouds fine at 70:30 which leaves a little more head room for flavourings.
You might try a more complex blend with lower percentages, I'm using this at the moment

To make 30.0mls @ 3.0mg Nicotine(Mls)
Base Nicotine - 1.2
PG : - 2.2
VG : - 21.0
Fa Vanilla Swirl - 2.7
Fa Dragon Fruit - 0.9
Fa Aniseed - 0.9
Ddl - 0.2
Ccw Cream - 0.9
Total Flavouring - 5.6
Expected PG:VG Ratio - 30:70
Actual PG:VG Ratio - 30:70
Which uses a vg base, as you can see you could up the ratio as there's plenty of head room of additional pg. It was meant to be close to the flavour of venus in vapes but its surpassed that and become my adv.
