Is the cyclone bf pin sliced or Allen from Tom? If sliced how does it squonk? Any leakage? I'm a little wary of sliced pins
I have a cyclone afc modded by Tom. He does quality work with anything he does. Can't lay my hands on it at the moment or I be able to answer your question on the modding technique. I believe he drills the center of the pin rather than slot the side of it. It does, however, squonk just fine - no issues. Note that there are 2 versions of the atty deck, and one is more concave than the other, which assists squonking even more.
As for the atty itself, I find that while it's still a flavour-first beast, the afc cap enlarges the chamber over the 'original' cap and mutes the flavour relative to that design. Still good, mind, but I actually prefer the non-afc cap with it.
It's a great little atty, BTW - sturdy, good connections. Even the afc version is not really for clouds, tho. IMHO, this is one of the 10 best small chamber squonking (when modded) atties ever designed for flavour.
