As usual, thanks Don. I'm actually at the point where I'm really, really, really attempting to learn self control and not buy any more new toys too soon. That is, until I decide on a variable voltage
mod.

You do make that Riva set up tempting since I use 901 LR attys as well.
Sanford, I think it was 5/23/2010 the night I discovered ECF and learned about true
vaping. I had wasted almost a month with a Luci set up before. I didn't learn LR attys were a newer innovation until a couple of days ago.
I find myself carrying around my 5v 510 PT to more and more places. I mainly use batts when out and about. I use the PT in vehicles. I also use 901 attys with an adapter on the PT. I have come to the conclusion that I'm not going to get the TH I was looking for. That's been evasive even when I vape some of the high mg nic samples I'm sent.
The most important aspect now is smooth flavor-able
vaping. For that reason I prefer the 901 over the 510. Not crazy with its vent hole though. I'm a dripper so I'm not interested in carts or cartos. My "current" working hypothesis is that a low maintenance variable volt mod would best suit my needs as I've found some juices carry flavor better at a certain voltage.
After a little over a month, I no longer feel overwhelmed by the wealth of information, techniques, etc. to get acquainted with but I am most definitely still a newbie when it comes to experience.
