Sorry to take so long to reply. PowerTech props makes several low-rake sternlifting props, not too dissimilar from the one they custom made for me. (They cost a lot less than custom props, too.)
PowerTech Propellors
The M250 series have lots of sternlift, but not the best for holeshots.
The UN200FS 4 blades are very good for V6 engines on the 20'. They are quite like the Mirage props.
