Ikelite D200 Housing

My Ikelite D200 house with flat port is 4 pounds negative. I would rather lose th 4 pounds than add bouyancy. Does anyone know of a tray system that works with UCLS arms and this house where I can lose the pounds?

Ultralight makes a tray and handles that work quite well with the Ikelite housing. Not sure how much weight it cuts down, but it's something. These handles are also adjustable (in and out), which is nice.

Cheers
