"For straps and other miscellaneous items, try this guy out in Idaho"
Hehe...That made me smile because Paul Gibson (directly above your post) runs Arrowhead Equipment. =) Small world, eh?
I love that our collective communities...both BPL and HF...have such awesome cottage industries that are made up of helpful (and ACTIVE) members on the forums. Talk about customer service! I own a KAQ underquilt from Paul at Arrowhead and an INCREDIBLY light three season top quilt from Tim Marshall (above) at Enlightened Equipment. Review of the top quilt to come SOON.
I agree that straps and whoopie slings (as they are known) are light enough and strong enough to be used exclusively. I have even converted my Hennessey ULBA to use this system. I am going to convert my Grand Trunk Nano 7 to use them as well for those times when bugs are not such a factor (which is a short window here in the South East).
