Yea, in a crash not much will keep those rotor blades from slapping your tail boom.

I've been using the CF blades for about a week now, I'll never go back to wooden blades. The CF blades have already taken plenty of abuse and they look good as new! They're polished with some nice sealant or clearcoat that adds an extra layer of protection, so it will take quite a lot it seems to start to shred the blades. They're also thinner it seems than the wooden symmetrical blades, so they fit in the blade grips without any trouble. Also, they're lighter I believe, because I've been getting much more consistent performance with the CF blades than with the wooden blades, but they also don't flex like wooden blades so that probably contributes a little. The head speeds of micro helis are around 2700-3500 rpm I believe, so that flexing makes a much bigger difference than it does on a larger heli where the head speed is around 1800-2200 rpm.

Seriously, you need to check these rotor blades out. They're just about twice the cost of wooden blades at $30 a pop, but they've already outlasted two sets of rotor blades for me, taking a few dings which would have ruined the tips of my wooden blades by now. Strong stuff, it is.

A side question: are there any heli sites that have basic tutorials on the basic maneuvers necessary to perform heli aerobatics, be it a loop or a snap roll? I want to get into this stuff soon....

Of course the best way to learn would still be a simulator
