I've kept mine pretty much stock. Sometimes, I remove the biners and use the loop in the original rope suspension with the marlin spike hitch in my straps.
I like the attached sack and I like the strap and buckle. I don't mind the stock rope. I don't like the stock carabiners.
I'd say, use it stock for awhile and determine if the hammock is "too heavy" or "too bulky" for you and then start modding. Some folks even cut off the "wings". Whatever. I guess that's why ultra-lighters are called "gram WEENIES."
