Hi. I always keep a new set of strings in my bag, so i bought the best strings available in my town: D'addarios XL-5 regular gauge. My BB75 came with Carvin strings .045, .065, .085, .105 and .128. The D'addarios are .050, .070, .085, .105 and .135. Any advice about these gauge differences? Should i get Carvin strings or are the D'addarios OK? Thank you.
