I made a pad choice for my BB. Following Brandon's direction, I decided on Landau Foam at a1foamandfabrics.com as a much cheaper and very close alternative to the Minicel at foambymail.com. I ordered 3 yds of the 1/4" x 60" (more than enough for 2 pads with cutting mistakes) at $21.00 vs $56.00 for (2) 48"x72" pcs of the Minicel. This will allow me the option of doubling up my pads on -20 deg nights. Thanks Brandon! I will eventually still end up with an underquilt but for the time being this will give me an inexpensive start to my trial and error process.
