NO, using a larger wing with a drysuit may even be counter productive! The wing lift is used only to counteract the weight of the cylinders & valves plus the backplate & harness. Of course most divers will also be carrying additional weight to compensate for the buoyancy of the drysuit, perhaps quite a lot more if wearing thick undergarments for diving in cold water. However, do not plan on using the wing as backup buoyancy in the event of a drysuit flood. Instead, the additional weight to compensate for the drysuit must be configured to be incrementally ditchable in the event of a drysuit failure.

Conversely, while some divers consider the drysuit to theoretically be backup buoyancy in the event of a wing failure, that's not best practice either. In reality, depending on their orientation in respect to the surface, many divers would find they have to so over inflate the drysuit to compensate that they lose mobility in their arms and may feel choked at their neck. For backup buoyancy in the event of a wing failure, we recommend selecting a dual bladder wing design.
