twin independents that is. but which ones?
in the following table, the column "tanks and weights" corresponds to the weight of the (empty) tanks plus all the weight i need when using my drysuit with light undergarments (one layer of fleece). at the moment i mainly use a 95 catalina 240bar (plus a luxfer 80) so that would be the more accurate estimate for the weight needed.
tank | capacity | pressure | cu ft | weight | b empty | tanks&weights 1
| tanks&weights 2

faber | 12.2 L | 232 bar | 100cf
| 13.5kg | +1kg | 21kg (12lb lead)
| 34kg ?
|
faber | 10.5 L | 232 bar | 85cf | 10.4kg | +1kg | 16kg (12lb lead)
| 26kg ?
|
catalina | 11.1 L | 207 bar | 80cf | 14.5kg | +2.6kg | 24kg (18lb lead)
| 38kg ?

catalina | 10 L | 240 bar | 85cf | --kg | + ?? kg | ?? | ??
|
catalina | 11 L | 240 bar | 95cf | 17kg | +1kg | 23kg (12lb lead)
| 40kg

"tanks and weights 1" is for single tank, "tanks and weights 2" is for doubles with some effort to take into account the extra regs. i use
this website to calculate buoyancy characteristics, so the numbers are not terribly accurate.
