Alfista, alfisto...

[Dana Loomis <dloomis@domain.elided>]

>is it "alfisto" or indeed "alfista"?  

it's alfista, regardless of the gender of the person referred to.  

things get really exciting with plurals: a crowd of male enthusiasts, or a
mixed group of men and women, are alfisti, while a crowd of enthusiastic
women are alfiste.
