I've tried a ton of short- and medium-scale strings (both fit my Eastwood K-200, depending on manufacturer), and in both flats and rounds, the big problems for me have been evenness of tone up the neck on the E string (a problem on many long-scales as well) and evenness of tone across the strings, with the E string again as the unmatched one. I tried the short-scale GHS balanced nickels and found them to be really as-advertised: much more even up the neck and across the strings than anything else. So unless you really want flats, I think these are a good option, also because the evenness allows for finer EQ tuning (in my experience). Just my two cents! For what it's worth, I actually haven't been much of a fan of other GHS strings, these stand out for me.
