I'm a regular user of Fomapan (under the rebrand of Arista .EDU Ultra), but I wouldn't choose it for pinhole -- it has some of the worst reciprocity characteristics going. It starts needing extra time at 1/2 second, and then needs 2.8x for each stop instead of the more common 2.6x. By the time your metered exposure is up to a minute, you're at a corrected figure of 8 minutes.
For everything else i do with silver image B&W film, Foma 100 and Foma 400 fill the bill. Same emulsion in 35mm, 120, and 4x5, available in bulk rolls in 35mm (brings the cost down to about $3 for 36 exposures), and only a dollar a sheet in 4x5 -- in each size, about half the price of Kodak or Ilford films in the same speed.
