What is your experience level in this regard, just out of curiosity? How many people have you actually seen ducking facing the top shooters? I've never seen it - not that that means it doesn't happen. But it's always been my experience that "damn good shooters" seek out the chance to pit themselves against the best, just to know where they really stack up.
I think Duane is quite correct, any shooter who "ducks a match" because there are better shooters there isn't much of a shooter. I would much rather shoot with better shooters than win a piece of paper or wood, the experience is much more valuable than a prize.
