Up date on previous review. After several days using this string found that it did lose tension quickly and because of it's "slick" feel the strings moved around a lot. Maybe using the 16 or 17 gauge would be better but won't be paying this much to experiment.
Was using Babolat Tonic in a Hybrid with Poly but since the price of Gut is still going up decided to try this instead. Expensive for a synthetic but as close to the gut feel for about half the price.
