Hi Steven it depends on your running style.
What are you currently running in?
I am not too clued up but it seems a little strange: Cushioned shoes are good for people with high arches and do not pronate very much. Heavy runners tend to pronate a little more though (not neccessarily a bad thing.
I do not think you are a particularly heavy runner.
I am not far off your weight and I use stability shoes as they have good cushioning and durability. I have found since using these shoes I have had fewer injury problems.
My current favourite is Asics 2070 which is great, I have no problems in it at all and is very adaptable.
