Depends, on if it was designed with a loose leach. Don't know anything about last century Tushinghams, but most wave sails were loose leach buy 97, some a few years earlier. That's what lets the head twist off and give good top end. the more downhaul the more it can twist.
Trouble is the non loose leach sails weren't designed to have so much downhaul, if you downhaul them to try and make the leach loose, you're likely to do serious damage to the sail, (as I found out on an early 90s sail logic). And the leach probably wont go loose anyway.
The newer fat head sails twist easier and with less downhaul, but they're not a quantum improvment, over a good loose leach from last century.
