FYI. Carbon Fibre props are very strong and generally very rigid right up to the point they explode into sharp shards. Do not use CF if you do not need them, they will still break.
I second the recommendation that you seek out and fit a prop saver for your craft. Also please ensure that you cut the throttle when landing.
If possible, try extending the nose some. This will increase the leverage, thus making more use of your weight on it. Trust me, I had the same problem with my explorer, and it works like a charm. Good Luck!
