I have a similar Prince prop to trents. Mine is a 78x48" and his is an 80x42". We both have fantastic low end pull from the props with some trade off in top speed loss.

My Mangy Fox will max out, wide open throttle, at about 120 mph. My old IV-1050 with the 68" 3-blade warp taper and 80 hp would do an honest 125 mph cruise all day long. But I can sustain 2000 fpm climb on my 105 hp zipper.
