All my days in a daze...
But even more technically it dry fires so not exactly the perc cubed scenario.
I've asked a couple of peeps who use the same sorta setup, an the only real functional difference I could figure out was that it effectively reduces the volume of the downstem a bit.
I wouldn't say there's anything wrong with using a downstem in an ion, just that I personally wouldn't be expecting the downstem to be doing anything other than act as a reducer adapter.
Ahhh, that makes sense. Hopefully you saved @TrAin x Wr3cK some cash.
