I think this is an excellent wound gut A-string. During the Fall, Winter, and Spring, I use a plain gut A-string on my Guadagnini and Vuillaume, but in very humid climates during the Summer months I use the Pirastro Eudoxa A-string, which is the best out of the Eudoxa strings in my opinion. The Eudoxa G and D are inferior however to the Pirastro Oliv (wound gut) strings which are far better. But the Eudoxa A, is a much more stable string than the Oliv A!
