Well Stu, you reef for the new anticipated AWS before you change course upwind.
But of course, if the reefing guide for this new 420 is for true wind, then true wind it is. It is safer legally for the company to express reefing in true wind as that is more conservative.
Typically, reefing to TWS downwind or reaching will have you under-powered while reefing to TWS upwind will have you over-powered. At least with my cat that is so. A less performance oriented cat like the Lagoon
may have less of a difference between AWS and TWS.
