Fuzzy c-means -- initialisation?

I'm implementing a fuzzy c-means clustering routine -- following p.360
of G.J. Klir and B. Yuan, 1995, Fuzzy Sets and Fuzzy Logic, Prentice

Is there any agreed `best' method of initialisation of the memberships?
-- presumably best in the sense of faster convergence, I assume that
local optima is not a problem.

At present, I intend initialising as per my k-means clustering routine,
i.e. randomly allocate class labels; for fuzzy version, I'll simply
initialise memberships to {0.0, 1.0}.

Many thanks in anticipation.
