Just curious: why do so many people want to get a Cat C license? What that means is that you're signing the aircraft as being fit to fly at the end of a heavy maintenance check, ie. you're staking your reputation (and license) on those others who've actually done the work and you're saying that you trust their work enough to put your signature to it.
Also, I get the feeling most Cat C guys are also in the MM kind of positions, meaning you'll never be on the tools. Personally, while in aircraft maintenance, I'd rather be on the tools than riding the desk any day!
