How do you intend to use it? If it's going to be a gun you carry while covering a lot of ground (walking) I'd say go with the 16 WW as it will be lighter. If you're mostly going to be shooting from a bench or stand and won't be carrying it all day then I'd opt for the Predator. I would also lean more towards the 16 if you live/hunt in a very damp or humid areas.
