Thinking about it, you're probably best served with either Labellas or the TI for a Cream sound. Labellas were what bruce played after all. They are not as stiff as Chromes or Rotos, but not unnervingly soft either. That is what TIs are, but of course you can also bend them like hell (and they hold pitch well) plus they put an emphasis on the mids which also plays into a Bruce sound direction.
