I thoughly enjoy not having a weight belt, and it was my trimix instructor that (like many before him) told me to loose the weight belt. It's uncomfortable under the tanks, the lower back is a bad place to carry weight and the risk of losing or forgetting your belt is a nuisance.
I dive dry in very cold water (undersuit like the Michellin man), so I have a lot of weight, but no belt & no harness. My back plate is 5,6 kg, and I have 3 kg between the twin tanks. If I needed it I could still add 2-3 kg along the spine of my backplate.
YOU ? ABOUT THE BUBBLE
Air gets around incredibly well; I'm still amazed they've made a zipper that actually holds it in. I seriously doubt you will notice a difference in how the air in your suit moves w or w/o the belt. This is esp. true with a neophrene suit because they don't seem to shrink wrap you nearly as effectively as a membrane suit.
