Re: turning point, michigan, amita or hustler?
I've got a TP hustler alum 21 pitch. They are more agressive than the orig Black Max 21 alum I had so a little slower on top end. They chip easier than I am used to and because of the exhaust holes, my I/O is louder. The big benefit is they bite well at least on my sig boat hull. I'd say based on my experience, they make a nice spare prop.
