i've got my aga t2 set up with about a 3cmx5.5cm wick and a 3/4 wrap of ribbon wire. i have to be careful when i drive and vape because i can't see out the windshield with all the vapor. i'm planning on stepping up to a z atty just to finish my zenesis 2 piece.
the igo-l in my experience is an awesome dripper rba and i'm probably going to get an igo w to try dual coils cause damn it's hard to drill another hole into the igo-l cap.
i have my aga t2 drilled to 3/32 which is too much for most but i like it there and my igo-l to 1/16.
are you referring to the air hole?
