Lp95 can hold roughly 8 lb of nitrox. So given you can ditch all but one tank you still have 22 lb of lift left for the DS failure. Depending on your undies some of your weight must be ditchable. Doubles inherently have less ditchable weight in form of another tank bands and manifold so they need a bigger wing to accoint for that.
Redundancy is needed because of lack of ditchable weight, not extra wing volume.
I would consider taking an intro to tech course if I were you. I think you're missing some fairly important concepts to a technical gear config.Well , doubles setup has more non ditchable weight that compensates for the dry suit positive buoyancy. Should the dry suit fail the wing has to be able to carry that extra weight that you cannot ditch.
Say I dive double HP130 with a drysuit that is 20lb positively buoyant. All my weight will be non ditchable. So I would need 40lb+ of lift in the wing to account for the case when my suit fails. If I do not have doubles but rather side mount I would still need those 20lb of weight which is this case can be in a form of ditchable weight so if my suit fails I can ditch say 10lb or more if I ditch the tank with the gas. So my wing no longer needs to be 40+ but rather 30+lb.
