I might go back to 75/25 on my next order as well. I've stepped down to 6mg and hopefully that'll help get some of the ol' throat hit back. I also find that more VG tends to change the flavor somehow... maybe more sweet?
If you and Denin go to 75/25, you will notice a huge difference!
I got 50/50 my first order and didn't really like it... The vapor was good, but the flavor wasn't really there.
I got a sampler with 75/25 and flavor shots and it works like a champ now. Red Energy is surprisingly good, and the vapor is really hot/strong. The throat hit is great as well.
Overall, a 50/50 is decent enough with very strong flavors, but at 3.6 volts it doesn't really hit that sweet spot that a 70/30, 75/25 mix does. (Also, 60/40 isn't that bad, pretty good stuff!)
