Here's 2 occlusal composites with Clean and Boost, Bond Saver D, Superb, Titan Flowable and Exquisite
I'm using Bond Saver D with Superb, applying it after etching to a dry surface, and before placing Superb. With the Surpass universal adhesive. I'm placing Bond Saver D after Clean and Boost, rinse and dry, and before Surpass 2. (I've replaced Surpass 1 with Clean and Boost to do the etching). As I understand it, Bond Saver D is re-wetting the surface and protecting the collagen fibers from proteinases.
