I like a rib that allows me to better 'look through the gun' or to allow the gun to be ghost like so I can better see rising targets such as trap targets and teal targets. Maybe that's why you like a slightly raised rib better? Some of those super high ribs on trap guns, you know, the grotequely high ones, I don't care much for them. I used to have a high rib Perazzi TMX....I never could shoot it as well as the lower rib TM-1 guns. The sight picture on the very high rib guns is bizarre to me. The English believe 'closer between the hands' is best. I bet they are right??
