Well, I just got back from the LDS here. I just ordered 2 LP85's (had to order them together to make sure they're the same size for future doubling) & a AL40 pony bottle. Lots of $$$ of course. Right now I'm going to dive the LP85's as singles. My instructor suggested I stay with them as singles, to get used to the weight & then double them up later this summer. I talked at length about not wanting to do to much at one time & this was decided to be the best solution. I'll Be in doubles by the end of the summer.
