I don't use RBA's any longer, I couldn't stand the wicks fouling. I use RDA's on my REO to drip, you don't get the flavor loss which is exactly why I bought the REO and use the RM2's. Cartos and RBA's have way to much "stuffing" to foul. A friend just got an ego style with clearo, which leaked right away and had those long wicks. I congratulated her on quitting smoking and secretly thought, "I am so glad those days of hanging wicks, flavor loss and leaking are OVER!"
I also tailor my DIY, and found I can use a lot less flavoring with the RDA's. Thank you for reminding me of this, because if I make my friend some juice I am going to have to figure out what I used to make for RBA's and clearos!
