Go with a steel rudder, I think most people would agree. I have a steel wedge rudder that came from Glenwood Marine and the boat steers better than ever. If you get a steel rudder you will have to take off the chrome if you plan to race.
Most race sanctioning bodys want all steel and no chrome under the water.
Besides it looks good.
