Weight belt for Dry suit use??

[Minnetonka]

Hi,

I have been diving for 35 years and only picked up a Dry suit a couple of years ago. I have been using my 30 year old fixed weight belt that has the weights screwed in to the belt to prevent movement. When I use this old belt with my dry suit, it tends to slip around and the buckle ends up on my side. I have to add weights to the pocket of my HUB (BC) and since there is only a pocket on one side, I am a little lop-sided. I have decided to purchase a weight belt that I will use just for dry suit diving. What would be the best weight belt to use for dry suit diving? I have heard about some belts that would have neoprene in them to expand and contract. Are these any good?
