Hannabach strings sound great on my classical (Takamine EC132sc), but I could not find a set that sounds good for flamenco. It seemed like the trebles were just too dull, and the diameter of the trebles felt a bit too large. The responsiveness left alot to be desired. But, in all fairness to Hannabach, I only tried the Flamenco series on the Yamaha.
Give those Savarez 500CJ Corum New Cristals a try. The bases are some of the clearest I have tried. The trebles are also very clear and responsive. The diameter of the string as also great . I seem to be able to get the rasgeados to growl easier with these strings.
Alot of flamenco players I know speak highly of the D'Addario strings, and one in particular recommended the T2 trebles. These trebles are great, I think. What I mean is they have almost every quality I look for in a good treble, except a little too much in terms of their responsiveness and percussive qualities. I have the Hard tension on my guitar currently w/ Corum basses, but I may try a lower tension next time.
There is this really fantastic flamenco over at another forum by the name of Richard (Ricardo) Marlow, and he recommends the LaBella 820B, which I agree are a great sounding string. They find their way onto my guitar from time to time.
