I'm almost two weeks into my new Christopher carved top and love it more every day. The helicore hybrids, however, are somewhat less exciting. The G & D have calmed down quite a bit and sound less metallic than they did. The A & E have calmed down as well but not to the same degree. The A string is noticeably more growly than the other strings. The growl, however, is tinny and metallic sounding as opposed to deep and growly. None of the strings are particularly loud but the E seems to produce even less volume. I plan to keep the strings for another month or so in order to get to know the bass itself and make a more informed string choice. (Not to mention that I broke the bank, so to speak, on the bass itself) Buying just two strings would obviously be more affordable than a whole set. Has anyone out there mixed Helicore Hybrid G & D strings with other A & E strings with good results? I'm not sure what the tension on the hybrids is. Thanks . . .
