We do not offer any plate pockets or pads. Pads are not really required, and storage between the plate and the diver is:
1) Quite hard for many to access
2) DSS plates are by design quite flat. That moves the tank closer to the diver, but limits the available storage volume
My solution for lift bag storage, and what I recommend to DSS plate users is two bungee loops along the bottom edge of the plate. Roll up the lift bag and secure across the bottom of the plate. Make sure the crotch strap in under the lift bag.
This allows for easy deployment, and even permits restowing the bag (with a bit of practice

)
~20" inches of bungess is pennies compared to plate pad / pockets that usually end up lonely in the gear box.....
