For the most part, it comes down to personal choice, just like radio systems and engines.

You can break an APC just as easily as you can a wooden MAS if you hit the ground with the prop on landing. That's just a way of life. And, that's why a lot of us have a quite large collection of props.. you know.. like potato chips, you can't buy just one!!!

There was a time when I was buying 10-7's by the bag full!!!
