Interesting take. So, if you had a 510 adapter only, what would your second be? 801? 901? My 510 is my daily vapor and I have a Prodigy 510 on order so your take supports what I was hoping. I already have a couple of true 801 atomizers on hand, but I'm not married to the idea of making the 801 my second adapter choice.
Surf, up until Thursday morning, when my Janty Stick (801) kicked the bucket, I had been completely enjoying have both my 510 and JS-801 side by side all day long. The vapes are different. 510 has a tighter draw, and denser, harsher vaper. The 801 is a lighter draw with cooler, lighter, but still prodigious vapor. At any given moment over the past three weeks, I would be hard pressed to say which one I liked best. I ordered a Prodigy 801 plus a 510 adapter, and can't wait to try out both attys on the Prod-bod.
Congrats on your confirmation by the way.
