Out on Dingle I used the Eureka Backcounty1 tent. My Scouts gave me this tent as an end of the year gift last year. It weighs 3 lbs 14 oz, which is relatively heavy for me, but it's sturdy, holds up well in wind and rain and is free standing--unlike my Spitfire solo--2lbs 14 oz + all the patching I did after the encounter with the cat so probably like 3 lbs even.
Lately, I've been thinking about tarps. This isn't a very attractive option for me in Florida--due to tick-carpeting and mosquito clouds--but I'm thinking that once I'm out of this (God-forsaken) state that tarp-ing will be more of an option.
If a tarp weighs 9.2 oz plus say 3.2 oz for stakes (GoLite aluminum V stakes), 3.2 oz for a tyvek ground sheet and another say 6 oz for a rope that puts us at 21.7 oz, or about a pound and a third--way less than half of the Spitfire's weight. If bugs really were a problem I could throw in a bug bivy for another 14 oz. For a total of 35 oz or 2 lbs 3 oz I could have it all.
