All I vape (without having issues with VG) is 50/50. And you're right that it's been  made less available.  The good old days when PG was predominant!
I've been mixing my own stuff recently, and except for NETs, I haven't bought  many juices recently.
That said, ECBlends was very flexible with %'s and had tons of flavors.
I hope they're still doing it.
