I have a Manuel Rodríguez FF cutaway with dominating basses and weak trebles. I tried the trebles of the Savarez 500 ARJ set, which pruduced a better dynamic balance than nylons, but not a good sound. After that, I tried a treble set of CARBON LINE Rot (red = High Tension) together with cheap but good basses (OEM brand of RC strings RC10 / HT) and now it's perfectly balanced. Especially e1 is very assertive without the "plastic" sound of some brands. As a matter of fact, it's the loudest e1 I've ever heard on that guitar.
I don't know where you live: CARBON LINE is available at Schneidermusik, Germany or maybe you could ask the manufacturer where to get it in your country: https://www.kuerschner-saiten.de/
