Okay, just to clarify. YES It is pointless to put volumizers on the old model angels. They put them on the Dark's just for looks, and so that you can have that more custom feel.
Mark,
I wasn't saying that BOTH volumizers were usefull on the LED, I was just saying that back in the day when they had the original LED internals one volumizer (on the LPR side of the marker) aided somewhat in lowering the pressure, as the internals did not allow as much air flow as the ones to follow and it put a larger volume of air behind the LPR.
Okay then, it's settled. Forget about a volumizer unless you've got a Speed or A4, or unless you find one that you think looks good with your angel, because they're as cosmetic an upgrade as say, the sightrail
