I received a new set of strings to test from Pirastro today. They are silver wound guts designed specifically for pizz. The winding seems different to the silver wound Eudoxa's....more of a roundwound but still quite smooth. Very dark blue windings on the ball end. Pirastro tells me they are ready to launch these strings worldwide. Initial impressions since I installed them on my 60+ year old King Mortone plywood are that they are very easy to play and are a bit brighter and have slightly more sustain than the Oliv's or Eudoxa's I have used. Pirastro also sent me a new nylon wound gut G to test ( like the Golden Spiral) but I have not tried it out yet. This is not the same string as the G that comes with the set I was sent. Maybe they are planning on producing a nylon wound G and D like the Golden Spirals to go with the silver/gut A and E as an option....or perhaps they are looking at a set of nylon wound guts. I'll have to check. I will post my impressions on this list in the next few weeks after the strings have been played in and after I have sent Pirastro my assessment. Just for the record.......I am not a dealer or in any way connected to Pirastro. Strictly an amateur player. I e- mailed some string questions to them a few years ago. Shortly after that they sent me some Obligato's to test before they were put on the market. These new silver wound guts are the first I have been sent since the Obligato's. Martin Chapman.
