Great discussion of sail shape. Many folks could benefit from proper sail shape and flattening their sails before they need to reef.
How much does heel contribute to weather helm? Since the theoretical hull speed is based on water line, will the leeward side (with a longer longer line) not be able to generate more speed than the windward side; ending in a round up? Shifting crew weight on a race boat is a common practice. In heavy air to windward, in lighter air to leeward. Race crew also tend to change foresails before reefing the main.
The "textbooks" use CLR and CE and tell us to reef the main first, then foresail, then main, etc.. But in my experience a foresail change will eliminate heel and reduce weather helm.
