Without sounding pretentious, I think that a 60 grams Flying C might have a far too heavy weight, whatever its expected use! I caught my best ever salmon (47 Ibs on the Vosso in Norway, under a very high June water level as you can see on my avatar) on this spinner, which gave me quite a number of good fish over the years, when I spinned!
Here is a link (English version) to the firm which invented and commercializes this lure.

You will notice that their maximum weight is 25 grams! I don’t know if they are still in business, but you can check, if you don’t find a local producer!
For the «history book of salmon fishing», I can mention that the «Quimperloise», the original name was changed to the «Flying C..» by Connie Corcoran, famous ghillie of the Blackwater river in Ireland, during a very «wet and sprit full» party at the Blackwater Lodge hotel in Ballyduff (I was at the party!) after a very successful day by some of of his British customers! Conny got hold of this new spinner concept, thanks to a gift of French anglers from Brittany!


Good luck with your search and tight lines in Chile!
