I was always taught that a port and tongue groove are two separate things. (am I right?) For example, on a Kimblewick there is a tongue groove which takes pressure off of the tounge and gives extra room for it. A port on the other hand is designed to "touch" the roof of the mouth when activated by the leverage applied. Tongue grooves are gently sloped where as a port is quite square in appearance and can actually be quite severe. Am interested in any opinions on this.
