I have a 50/50 blend. I find that sometimes i do not enjoy that much of a throat hit. but, i am worried about losing flavor by decreasing the amount of PG in the blend. I wanted to pick up one particular flavor in 20/80, 50/50, and 80/20 to see the differance between PG/VG first hand. If you only purchase the 5 ml bottles itll run you ~15 dollars to know which you like for sure.
Granted, you will be almost throwing away about 8 dollars but in my state that is one pack of analogs. Id say it is worth the cost of the experiment to insure that you are having a pleasurable experience.
I plan on doing this before my next major purchase of fluids. Hehehe, this way i dont blow a more significant amount of money on fluids while conducting my little experiment at the same time if it turns out that i prefer something other than a 50/50 blend.
