Got my new Spitfire and put it on the scale (haven't used it yet).
Body+fly+poles+sack = 2 lb 14.2 oz
Included stakes are pretty good for OEM in a $65 tent: strong and lengthy. But .6 oz each (10 included).
I think 6 stakes minimum are required (maybe 2 extra to tie out the fly, but I'm not sure those are required). Using 6" titanium takes at .25oz each, would yield a total weight just under 3 pounds.
