My vote is for Ilford Multigrade FB. I've used that for many years with excellent results. I recently tried the Ilford Warmtone and was well pleased although in Dektol it was not as warm as expected. I try to keep to one paper in different sizes since to me it maintains a consistency in a portfolio. For a different look I do pt/pd. Personally I stick with FB paper. In the past I tried various papers including graded papers each of which had slightly different characteristics however, my feeling is that regardless of the paper it is the image that counts.
