What works with what:

as far as big mast brands go, Fiberspar, Ezzy, Simmer, technolimitz, older NoLimitz etc are middle of the road bend curve and suit many sails.
You want to avoid Neil Pryde and Gaastra / mauisails as they are mast specific.
BUT if you get your first mast and sail at a ripper price then have to stick with that brand later (and it is commonly used or sold wherever you are) then what's the harm?
