True, me tackle is a bit bigger ("Wellington" keel) and the boat is heavy (Volvo 9hp ballast), but I don't have any issues with the ST compared to the pin head that was on there when I bought her.
Upwind, in moderate conditions I don't have any greater heel - so long as the leech is left open to get the twist required in the upper 1/3. Just need more outhaul and a bit less vang, and the sail really looks after itself. I would still reef at the same times once winds are over moderate.
What I do have is a small 'flattening reef' at 150mm (or 200?), that I use solo over about 15knts, that
