i thought friso 1-4 all taste the same?
well, at least it "smells" the same for me.
my take is, if your girl is OK with friso, just stick to it.
n dont have to mix the FM. i never mix, always give straight.
but if you wanna change, n feels that she prefers GAIN (which in the beginning she only took Friso, so dont see why she wont like it...), then switch lorr.
