I also have to mention the Gossamer Gear Thinlight pads. They are very light, a lot more packable than the blue WM pads, and offer really good insulation for the 1/4" thickness. They offer a wide/long version for hammock users. That has been my pad of choice for a long time. If you get the wide/long version it is best to trim it down to a mummy shape because it's almost to big for a HH and you could have problems getting it to lie flat.
