Testing Harold's sidemount travel kit (http://www.hlbdive.com/fr/accessoires-sidemount/122-kit-voyage-sidemount.html
) in Red Sea ( near Hamata, south Egypt).
config 1 S80 Tank, sidemount kit, no real tek config, diverite wing + harness, 1 regulator., 3 mm wetsuit, 1kg => very light config : no need to inflate the wing above 30m...
65 m max, solo dive
Deco based on slow ascending procedure + deep stops.
As a Britany ( atlantic ocean, western France) experienced diver, I can confirm that visibility, water temp, light config (hence no effort underwater) are key paramaters for not feeling narcosis, i did feel like a 35m dive in dark, cold, heavy loaded water.
