I just acquired a 168 gram, lemon yellow, prototype, 2010 PDGA Professional Disc Golf World Championships, Lemon Lake, promotional Innova "Star" Katana from "The Disc Depot" in Portland, OR. I already have a 175 Champion and a 168 Pro Katana 2010 Japan Open promotional disc. Does anyone know when these are suppose to be released to the public. I think the Katana is going to replace all of my turnover disc. They are fast and very under stable.
