Hi
I have two SS props for my boats.Both are prather a 215 and 220. They work great and look pretty. Good points,they are stronger and if you like a sharp edge,will hold it better. They do not weigh more. The copper props are available in much greater supply and types. Easy to work with and are good for every use. Both types will do the job .You just have to pick the right one .
