I don't have a lot of seat time with my 28 Pro ET yet but 1st impression is great hole shot and real good cruising prop. It seems to carry the boat real good too. I haven't got to try much for big numbers but the boat seems to lay kinda flat when you get her moving good and it seems to take more trim to get the bow up at higher speeds. I am working on my setup so nothing is etched in stone at this point.
Maybe the Pro ET lifts the back of the boat more than the 3 blade ET.
