Harry, from those, I have tasted only Valencia Pride and Ataulfo.
My plants are located in the island of Gran Canaria, but due to work I'm not living there. Those cultivars come from germplasm collection of a public research institute in the neighbour island (Tenerife). Yes, those are rather old school, but hopefully I go super new school in a few month ;-) Besides that, I'm still aiming for indian and pakistany mangos. I love that mangos and I think our hot and dry climate would be suited for them.
From what I've read, Madame Francis is supposed to be excellent tasting, but has lots of fibre. I'll give it a chance, if don't like it, it will be topworked...
