what should I go for - sails?

I have decided to ditch the original East cheesecloth sails on Morgelyn but am totally confused as to what are the best replacements. Whilst we sail mostly in light winds I still want something fairly bomb proof yet capable of giving the best performance from this great boat. What is your view, we use the self tacker by the way and I do not want to change that but will probably also add a gennaker. I know it is a wide subject and probably flogged to death but so are my present sails!!!!
