Finally tried a set of Mari 100p strings. They replaced a set of Augustine Imperial trebles with a carbon G string. The Imperials were very good, and maybe a bit richer in tone than the Mari stings. I think the Mari strings are a bit brighter, and probably the most clear sounding of any nylon strings I have ever tried, and the G string is not nearly as tubby sounding as most other nylons. The main guitar that I play can sound bass heavy and muddy in the trebles with the wrong strings. I have tried carbon trebles and they helped with brightness and clarity, but after playing carbons for a long time, I noticed that they did not have that certain richness of sound that nylon strings have.
Thanks to es335 and Peter for recommending these strings for guitars that are somewhat bass heavy. The bass strings are also very good and match the trebles well. Overall, theses are the best complete set of nylon strings that I have tried so far, for this specific guitar.
