You won't hurt the TT pro with that prop, even if you set it as lean as you want.

That prop actually loads the engine more than you'd think based on the pitch and diameter alone. First, it has the extra blade, but just as importantly, the blades are really wide, lots of area there. Compare that to a prop made for really high RPM like the pylon guys use. Those props have very narrow blades by comparison.

I forgot to mention, I also have a TT Pro .46, and while it's a powerful engine, it's not THAT much more powerful than the Evolution. Maybe a couple hundred RPM, max. Not the kind of differnece that would be an issue with props and over-reving the engine.
