Hoffmann vs MT propellers
 

Does anyone have any guidance in deciding between Hoffmann or MT variable pitch propellers?

I have just found out that the Hoffmann one has to be overhauled every 200 hrs which is every two years at my current rate. This seems quite a short life between overhauls and I was wondering whether MT ones are any better.

I also note that the MT ones have stainless leading edge vs copper in the Hoffmann. Again are there any advantages either way in terms of durability?

Many thanks
