Digital BW, The Print

I finally got my 2400 from Page Computer at the $675 sale price.

I've been printing on Epson Heavyweight Matte until now. I'm wondering
which of the Fine Art papers you'd recommend I try? I've not used any
for B&W.

 Also, any pointers on playing with the Advanced B&W controls on the
2400? Might there be an article on tweaking those>?

 Appreciatively
