Hello Cliff, I would profile the Harmon FB matte to 2880.  I was playing with a sample pack 
of Harmon fb matte to see how it profiled.  I was doing a 4MK approach which is 
somewhat grainy to begin with but the Harmon matte showed considerably more grain 
than than all of my other matte papers.  I think it has to do with the extra sharp coating 
and lack of dot gain relative to other papers.  The dot edges don't blend and stand out 
extra sharp.
