I loved pitch contests, but didn't find my agent that way. Regardless, they're a great way for fine-tunning your log line and they're just plain fun. It's nice to read everyone else's pitches and see what else is out in the world, too. Definitely have more than one strong pitch for #pitmad (if you don't get into pitchmadness)-- they're different things and Brenda Drake's website is a great tool for advice on that. Sometimes there will be a practice session for pitches or I bet you could post them on the SYW boards. Best of luck, and even if you get favorites, you don't need to send to every single one. Do your research and make sure that you're interested in them, too.
