I just got some Umbavapes WTA and it is EXCELLENT. I had forgotten what a decent WTA can do for me in really very minute quantities. I feel.... calm. I'd say it's rather excellent, rivalling Aroma's but at Mother's Milk prices or less.
If you are really having trouble, I'm fairly convinced that Umbavape's prices might convince you to try some. Although, there is a part of me that wonders if I should really mention it (I kinda want their prices to remain low) but praise is due, and all that.
AND, I'd really like for you to have an easier transition. If I hadn't had WTA (Aroma's at that point) while I was detoxing off tar and whatnot, I would have found a way to chew my own ear off. With that said, you really have to do what's best for you. I really vacillated on WTA as I didn't want to give myself a "crutch" especially knowing I was going to go the DIY E-liquid route, so ultimately it is up to you, and lots of people successfully transition without it.
Best of luck, either way.
