I hear ya....if going solo for just 1-2 nights, then I'm gonna be using this:

With my Rev X Quilt (23 oz), Neo Air Pad 9 oz, TI Goat Bivy 7 oz, plus stakes and guylines the tarp will likely be around 16 oz. Making it around 3.5-3.75 pounds. However, if its raining i'm still going even if its gonna be a slog, so I'll gladly haul the extra 1.25 poudns of the SL-5 along for a little more elbow room and protection out of the rain as after hiking for 8-10 hours in the wind/rain I find its nice to be able to just sit and hangout out of the weather completely for a bit. I know I'm a pansy for it though so no worries there.
