I agree Kent.
Elyse has vertical battens on both main and mizzen.
30-40 degrees to the wind, preferably stbd tack, boom 90 degrees to the mast.
We have marks on both sheets to enable positioning of the booms correctly before furling.
When unfurling the main we keep the foot taut by running the outhaul continuously and stopping starting the furler.
Reverse when furling, furler on continuously, outhaul off/on to keep it taut.
