I have one Matt, it's the all white painted unit. I've just ticked over 100hrs and it seems to give me a couple of extra knots cruise and it seems to be holding up quite well, given that a few of the other sensenich's have had a tendancy to crack on the backside of the blade, which is quite thin compared to the jabiru prop. my 120 climbs like a homesick angel, even at max weight. i noticed the other day with 1023 pressure, 29 deg oat, i was getting between 800-1000fpm climb with 2pob and max weight which i think is quite reasonable.
