Great quality strings with a heavy bottom end,i found these strings a little to heavy for my floyd rose style guitars at A440 but fine if dropped to a tone to D,No issues with using them on a fixed bridge.
Ive also used them on a 7 string setup by just moving the 0.54 to the low B and slipping a 0.46 in for the E handy if your stuck finding a set of 7's to use
Just as good a tone/feel and life wise as strings x3 the price.
