ok, good point. So one builds re-trimmable test props then you build a
prop pitch jig and heat and twist your competition props to the desired
pitch.

Same net effect.

SO rules are usually enforced quite literally, and one should always
comply with the "letter of the law" and figure out ways to do what you
need to do inside the "letter of the law". My strategy is to never
think that an SO judge (or a coach from a losing cometitors team) will
let you get away with anything that is not specifically allowed in the
rules.

Avoid disapointment, but be creative in your approaches to compliance.
  That is an unintended lesson of the SO competitions- rules is rules,
and rules always have loopholes. (I've never met an SO rule set yet
that was clear and unambiguous. English is like that. People are like
that.)
