Are you sure it came with stainless steel? Was it used? Almost always they ship with nickel coated steel. Stainless has a different color.
45-100 is like the 10s of the guitar world. 45-100 nickel coated steel is a good middle ground for everything. If you want slap, 40-95 SS will give you a little boost. Flats are awesome (especially medium gauge) for R&B, Blues, Motown, classic rock, etc. You can do it all with nickel/steel 45-100 or 45-105, going with other strings helps push you in each direction.
(I have SS on my active 5, nickel steel on my jazz and soon to be flats on my new to me P Bass)
It's new, I'm Sure it's the nickel coated, the cheapest thing that they can get away with.
