When I showed up at the field, I had a wood prop on my avistar. The guy who took my plane up for the first time suggested I get rid of it and install a nylon prop, he said they pull harder and there's no danger of the prop nut backing off. The guy who's refreshing me runs wood props on all his planes, and has no problems. I guess it's kind of a personal preference kind of thing.... I personally think wood props look better on an airplane, but that's just me.
