Have not had many situations where my Furlex (Selden of Sweden) was too hard to furl, except of course, when attempting this in any position other than head to the wind, in very strong winds.
I've resorted to using a winch once, during a sudden heavy blow and couldn't head-to quickly enough, without starting the engine. Strange though, winching in such a relatively thin line as the furler control line.
