Guitar strings (and drumsticks!) are guaranteed to provoke many a lively 'discussion' between musicians (and drummers - lol), but I'll give my thoughts for you to consider and/or ignore.
Flat wound strings are something you either love or hate. I hate the 'string squeak' you get from wire wound strings. I know that's partly down to technique (but I'm a drummer - what do you expect?). However, my Dad always used flat wound strings, and I've grown up preferring them also. You might get a little more treble from wire wounds, but you can also bet that from an amp or eq?
These strings were easy to fit, and very quickly 'settled in' (they didn't need more than one or two 'stretches' before they held their tuning.
Since fitting, the strings have kept reasonably good tuning, and played very well. If you want flat wounds (for whatever reason) then I'd recommend these.
