After my first discouraging encounter with flatwound guitar strings that were made by another well-known manufacturer (they were as dull and uninspiring as soaking-wet ropes), I decided to give these a try. I have no idea how those Austrians are able to make them this great, but I know that I will never use anything else but these 12s! Not only do they sound amazing, but they also do not seem to need much (if any at all) stretching out before playing because they hold their tuning really well right from the start. Personally, I like them even better after two to three weeks of daily playing because then they seem to become a little bit more flexible and mellow.
Finally, despite the packaging claiming that the ends are silk-wrapped, the wrapping is not actually made of real silk (according to the manufacturer), so these strings are suitable for vegans!
