I put a similar prop on my J almost 2 years ago. It is lighter, smoother, and better looking than the McCauley 2-blade. It is slightly slower in cruise, though, but in your case with a turbo I think it wouldn't matter since you can run higher MP if you wish while I'm limited without a turbo. I think high MP and lower RPM is optimal for the MT as I believe the blades were aerodynamically optimized for efficiency at lower RPMs due to noise concerns in the EU. Getting weight off the nose of a turbo Mooney is a good thing too as many of them need or use ballast in the tail to get the CG in the right spot.
I had severe trouble with paint eroding while flying in IMC with my first blades. They were repainted under warranty, and shed paint badly again. I insisted on some replacement blades and these have been better so far. /knocking on wood.
