I've been trying out different strings since the beginning of the year and while I certainly like some better than others, I don't actually dislike any of them (except maybe for La Bella 0760M's .110 string, which I never managed to intonate properly). Are there strings you actually dislike?
In general, I don’t like flat wounds much preferring round wounds. I absolutely hate (ahem) “vintage” flat-wound strings that should have been replaced decades ago.
