I do like APC, but latley I have really been liking master aircrew. Its really all your prefrerence in what you like and what your plane likes, dont worry about damaging your engine unless you DRAMITCALLY oversize the prop but then you would just notice very bad performance as the power cant swing the prop in the RPM range recomended. Try them all, dont stick to one brand, I like to try all kinds. Yes APC has the best rep, but master Aircrew has IMO nicer looking props.
