Bingo, most of us don't hesitate to tweak a spar to get a different nominal pitch (should say "pitch angle" in this case) one direction or the other. I used to think it was better to tweak from higher pitch to lower, but not so good from low to higher. So far, have no measureable evidence for that belief. My current theory about indoor props is that instead of worrying about any theoretical "optimal", it's better to concentrate on contruction excellence, meaning strength/weight, uniformity/shape. After you hit a certain number of "good" props, one of them should emerge as a great prop, for no proveable reason. But takes a lot of time to sort them out.
