This was the first flatwound string I've used. Love the sound and "thump" I get with them on a P bass. When your fingers get a little wet the strings get sticky--solved that with a little string lube. Absolutely no noise when sliding down the string, no longer have to think about string noise during transitions. Strings seem a little stiffer due to the winding but I was able to quickly get used to that. They do have silk wrap at the tuning machine end--was a little concerned about it fraying by the string keeper / guide. Just what I was looking for.
