If you prefer a jacket style then thats the one to get as a backpack or backplate will just bug you. When i dive in the tropics my rig is a backpack and wing with a UK4 clipped to a D-ring and bungied so it doesnt dangle similar to the DIR way. Have a safety sausage bungied to the tank and a small reel clipped to the waist D-ring. If i take a slate thats a wrist mounted one and computer and compass are also wrist mounted. Camera gets clipped to a chest D-ring if its not in my hand and for any night diving i run a canister light and thats on the waist webbing. You may dive entirely different but i hope this helps.
