Lot of discussion in a couple of threads recently about flatwounds - I've only tried them a few times but didn't give them a fair chance TBH. So, due to the prompting in the aforementioned threads, I'm thinking about jumping back in again and giving them a try. IIRC The Olympia brand strings used to be own/promoted by The Bass Centre a few years ago. They sent me a set of Roundwounds FOC after a deal went wrong. The Adagio I know nothing about, happy to learn more.. https://www.ebay.co
