Right in there with you for specs.
I use an ENO Double Nest and either a Hammock Bliss bug-net or the Eno bugnet.
Sewed an extra layer on the outside for use as a pad pocket and never had bugs bite me through the bottom.
Look for no-name types on Ebay and you can find ones that go to #400.
I picked up a spare for $15 w/ $9 shipping a while back.
The Kammock is supposed to fit us normal sized guys as well.
