I've bought several sets of VS over the years. I have several where the package is blue with Roddick and Clisters on it and then I have some that are green/gray that just says VS Touch. These are both 16 gauge. I'm wanting to use up the older strings first, but I'm not sure which one is newer. This is what one looks like: http://www.tennis-warehouse.com/descpageACBAB-BNG15L.html and this is the other: http://www.tennis-warehouse.com/descpageACBAB-BNG16.html and like I said, these are all 16 gauge.
