I'm gonna answer you with a question ... Do YOU want opening doors on that particular model? Don't do something because "it will help win a contest;" it probably won't. Do something because YOU want to and if it turns out right, enter it! Who knows, you might take home some hardware.
Before you ask, yes, I enter contests; mostly to have fun and meet folks and learn things. "Winning" is not a priority for me though I do have a modest collection of hardware to show for my efforts.
