Hello, Anybody here knows anything about this Prestoflex string set? It's a new product, I think, and the strings are available for sale from a European dealer; price sounds good (~110€ vs. the regular 145€) but I cannot find anything about the strings. Would like to hear some opinion before pulling the trigger. Hope I'll get some help, thanks everybody in advance! Regards, u. P.S. Of course, I'm not affiliated with Presto Strings or with the mentioned dealer, this is a genuine request for opinions.
