Full face for creeking and manky low water river running where scraping on the bottom is possible. Don't see much playboaters with a full face as it would most likely slow down the roll.... That Bell would act like a sail under water and your head would feel heavy and slow as you bring it up/around. The WW ones are small so they can slip thru the water faster. Least obtrusive/sluggish in the water would be a full cut predator with a standard cage.
