"I like the Tarp + Net Tent idea but I am going for full weather protection as well as bug protection. I am afraid I will not get that in a setup like that."
Depends. The size/shape of the tarp, and, if your net tent has a full bathtub floor.
For bad weather, and when I expect colder weather ( ~32F or 0C), I much prefer my tarp and net tent. The wife and I have been out in wildly changing conditions in late fall with temps in the 80F range when we started and close to 10F on the same trip after 5 days, 3 of which were solid rain. It kept us dry. Better than our Stevenson's tent, actually, because there was a lot less condensation. At just under 3lb, (tarp, bug tent, stakes, guy lines, hiking staff all add up to 44oz) it wasn't too heavy to carry and VERY effective. Just leave a space around it at near the ends for hi/low ventilation. For breakfast/supper, we pitched the tarp, but only staked the net tent. The bug tent was dropped for breakfast/supper. Soo, we had a dry place to sit and could cook under the tarp. Tarp was a 10x10. The tent was the Lair 2 nest (no longer made.)
