My only concern is trying to get use to the 801 atty's. When I had an 801 I never liked the light as air draw and I couldn't taste much flavor in comparison to the 901. Maybe it was just the one I had. Those two differences have never been an issue with the stick for you?
Exactly my concern with the 801 attys.
I ran the gamut of several 801 models, including the Kissbox. That light, airy draw just didn't do it for me. Even with the manual switch Kissbox at times I felt I was sucking air.
I really like the "tight packed" draw that the SD and 510 models give me.
