That is the beauty of these forums.
5 Years ago I was not looking for a feathering prop and I always find the forums online the best source of information. Real world users and real world conditions. Too many reviewers are being paid (directly or indirectly) or have a reason for a favourable review.
The only negative review I have found anywhere on the web for the Kiwi prop has been here and he never used one. So it sound really good
