Zone Alarm advice please

By default Zone Alarm installs as Internet zone on stealth mode and Trusted zone Med (sharing) zone. As it would seem to off better security with both in stealth mode, what would be the problems with having the Trusted zone in High (stealth) mode?

You wouldn't be able to access shared folders, printers etc, and no one else on the network would be able to see your computer or access shard folders, printers etc.
