EB strings and stratocaster

[Efin]

EB Regular Slinky 10-46 - 4 and 6 strings brokes in two weeks - both in point of bending on the stratocaster's tremolo. What the ...? What wrong? For example I used BLUE STEEL 9-46 for few month and all was Ok. Down half-step tuning.

Check your saddles. You may have a sharp edge cutting the strings.
