Of the Cisco 901, 510, and 801... no surprise that for me the the winner hands down is the 801.
Very nice 801 atty. Since sampling them, I've order a handful more of the 2 ohm 801s and have been rockin them (and a few Boge 2 ohm cartos) on my P16 ever since. The LR cartos are the first cartos I've tried that are actually satisfying, but they only last a few days before becoming some combination of foul tasting or super hard to draw (like all cartos I've tried). So that sends me right back to the 801 atty which is even more satisfying and can last for weeks with simple draining being the only maintenance required.
Like all 801s, the Ciscos can be leaky, but adding a little extra VG (emphasis on little) to thicken liquids helps with that in addition to making fuller vapor.
