Went to bed! As someone said the holes are just beveled and are plugged with alan keyed plug screws. If you're going to try the drip mode just remember not to put too much juice in at one time, because juice inevitably seeps through the plug screws (my reason for sealing the bottom sides of those holes with epoxy). And you're welcome! You helped me a LOT back when I was getting started with RBAs...very happy to finally help you in some way.

Yes I'm still vaping on pluid as well, lol, but I have found two other great juices! G2 and Shocker from G2Vapor...me and my pluid stash LOVE them!
and for Qorax...it's almost identically the same size as an AGA-T2. There is more room in the cap end though because of the flat top, unlike the AGA's slanted one.
edit- And it looks AMAZING on my PAPS...just saw you had two.
