Rob, you should ask the MT people in Germany directly.  My A&P is working directly with them on the 5-blade MT prop for the TBM 700/850 (now complete) and he says the technical support in Germany is excellent.  I'm sure you can find a web location for their main contact points.  As an aside, they went back after testing and added erosion strips to this 5-blade design and "bevelled" them into the leading edge so as to provide a smooth transition.   Those guys appear to be very responsive in Germany.

Another query for those out there who are already flying.
 
I purchased a partly built L360 kit some time ago, which came with a 3 bladed, constant speed, MT, composite prop. It has never been assembled, and is by now about 20 years old. Now that I am getting closer to completing the project I have been speaking to a couple of propeller shops. As I intend to operate IFR, I asked about durability of the prop when operated in rain. The response has been a little confusing, with statements ranging from “they are not designed for ops in rain” to “ they are approved for ops in rain, but nobody actually does so” to “they are fully designed to operate in rain and will be fine”.
 
I would appreciate any comments from those of you out there who have operated MT composite props, as to their suitability in rain.
 
Thanks again for your input.
