The thing is that people use a wide array of tanks on these units. Aluminum, Steel, 50cf, 13cf, etc. My CCR ready to dive (no lead) is 45lbs. A JJ with two LP50s is over 100lbs.

These considerations that you might want to ponder as you pick a unit.
I get that. My friend uses al80s for bailout

With a normal JJ in the sea I use between 2 and 7kg depending on the undersuit. A JJ with 3l steels weights about 38kg, slightly less than twin 12s. That is already quit a heavy thing. Using 7s or 8.5s instead makes it excessively heavy, at least for normal sized people, in my opinion.

You need to have a think about whether the bailout counts. Might you hand it off? Will it be positive when empty?

Mid-grade undergarments
72cf al bailout
Turtle fins - will be replaced w Deep Eddy's

I just don't log dives
Not being a sidemount reb user, but my 5 cents. Backmount KISS unit with 2l steel tanks, trilam drysuit, heating vest+ Subgear 490 undergarment (Large), rubber fins, lights, heater battery canister, and so on stuff. Dived mostly in cold waters (+4 - +8 deg.C)
for an hour typically. 6 kg of lead in reb case, 7 kg weight belt. Overall 13kg (sightly less than 30 lbs of lead).
BO not included (S80/7l steel/4l steel - according to dive site).

Not a Meg, but the JJ-CCR in all steel plate/cyls, plus custom shrink wrapped lead cylinder weights in the handle tubes, is basically neutral for cold drysuit diving at a land carry weight of ~40kg / 90 lbs
