telltales on the leach of the main to use as a guide in sail trim.
I guess my position (somewhat supported by North Sails' literature) is
that in light to moderate conditions you want to adjust angle of attack
(close-hauled to close reach) and twist to achieve attached flow over
the full length of the leach; with particular attention to the top of
the sail.  When it starts to honk, I'm usually using using the main for
heel control; dumping wind off the leach--and don't pay much attention
to the telltales, at least in the gusts.  This seems to make sense for
masthead rig boats with relatively large headsails (wrt the main), but
I don't know how it applies to fractional rigs or boats with largish
mainsails.
