Ok so i went to a guitar store and just grabed a pack of strings they were D'addario's and well i later realised that on the pack it says: Nickel Wound:Blues/Jazz rock and the thing is i dont play blues or jazz/ rock, i play metal and hardcore type stuff.. will these strings be ok for that cuz i thought i might wait and like switch them later or would it really matter.. oh and is it helps there .049-0.11 so yea... thanks

yeah, actually those strings are good for you, they're 11 gauge strings, they're heavier than 9's or 10's obviouisly, so if you do drop tunings you'll get a chunkier sound. the only thing is bending will be a bit harder. otherwise they're probably well suited to you
