Considering getting an aerotank and I noticed I see this pic:
and I've seen this one:
Are there two styles out there or is one newer than the other? And is it just cosmetic or other differences? I prefer the first one, but most seem to show the second one for the image they are selling.
And some say pt 2 coils work fine in this, others say you need to do the flip grommit trick. Wanted to confirm if it just works or need to do the trick. I realize I can buy a pt 2 and an air flow valve (which is actually cheaper) but it's nice if the aero does in fact work with both single and dual coils. And I really like the looks of the first image I linked so I'd prefer that over the pt 2.
