I love my Contrail. I've considered the Moment, but hear a lot about condensation issues. I was turned off by The One simply because I'm not all that keen on spinnaker-tear strength, noisy, etc. Though many people have them and the general consensus seems to be that The One is a great shelter. The Lunar Solo seems like a great tent similar to the Contrail in many ways, but is side-entry; a plus in my book.
And if you don't want to buy/use trekking poles you could always purchase ~2oz pole for the Contrail, The One and the Lunar Solo (no poles needed for the Moment).
But if you want to go really light you could look into Z-packs Hexamid with netting. The Hexamid plus a ground sheet would come in at a mere 10oz. Add a door to it for even more rain/wind protection and you have yourself a cuben, bug proof, storm-worthy shelter at only ~11oz (including a ground cloth).
