Well, if the internal airhole is that large, then I probably wouldn't like it. That was the change they made to the Achilles 2 -- the original Achilles has a very small internal airhole, about 1.5 - 2 mm.... the new ones have a 2.5mm internal airhole, and no matter how tightly I close the AFC ring, it's still too airy for me, can't get proper resistance to the draw at all. Fortunately, the new tank ring's threads match the old bases with the smaller internal airhole, so I'm using the Achilles 2's ring and top cap, on an original base. But it kinda burns me, since the Achilles 2 cost $98.
Nobody seems to really get "tight draw" anymore; stuff that people say is a tight draw, often turns out not to be -- Veritas, I'm looking at YOU. Also the Alleria -- much too airy, even with airflow closed almost completely. Magma, for me, is borderline; a little looser than I prefer, but I can tolerate it, because the airflow is DIRECTLY beneath the coil, so the flavor is great. too bad it leaks so much. I've seen pics of the new "Magma Reborn" and while they seem to have addressed the leaking problem by building up the airholes over the surface of the deck, they're much bigger now, so I probably wouldn't like it.
Internal airhole of NO MORE than 2mm, 1.5mm preferred;
airflow DIRECTLY BENEATH the coil;
airholes ABOVE the surface of the deck
Those features are what I'm looking for; no side air, no internal huge airhole, no airhole flush with the deck surface. The only thing I've tried so far that features all that is the original Achilles. Too bad they don't make them anymore, either authentics or clones.
