The factory strings on my acoustic were very heavy and also generated the most movement noise I've ever come across. I also needed to lower the action.
These string feel really nice, and produce a good sound, although it has to be said they also sound a little soft. I've no doubt there are other strings that ring out more, but these are fine for me. The balance of feel and sound is pretty good.
I'd be happy to buy more but I might also experiment a bit first.
