The tent I have, and would take if I were going for even a short tour is a Highlander Forces 2

Now, as it comes, it's heavy 3.5+ kg because of its steel pegs and fibreglass poles. But I swapped out the steel pegs for alu, and got some alu poles from
Decathlon (£14, from memory). This got the weight down to 2.3 kg, which, for a two man tent, is okay.
It's bombproof as tents go, which, while heavier than the real ultralite deals, is what I want from a tent. Lightweight is great, but if, in a storm, it flaps away over the horizon, then it's not such a good deal. I'd prefer a heavier, more robust tent.
This tent gets most stable tent in its class in Trail Magazine. There are some downsides to the tent itself - it can suffer from QA issues, and I found that I needed to add ties around the poles in the roof to draw them together and stop the inner touching the outer and condensation coming through.
But the space inside is exceptional. I have a NorthFace Tadpole, which is about £200 more expensive, and while it's maybe 500g lighter, it's lower inside, and feels flimsier, and generally more difficult to put up.
The highlander is two poles which cross over, so while not exactly a dome tent, it's self supporting. It's inner pitch first, but the inner is thickish material, so I don;t figure it that big a problem. And if it were really lashing down, I'd just put the poles in with the tent upside down so the groundsheet got the rain.
The porch is also a good size, and you could easily fit wet waterproofs and at least two panniers inside.
For me it's a great tent, if basic. It seems bombproof, if on the heavy side. And if you're prepared to spend a bit more and mod it, I think you'd have a great touring tent.
Of course, that's just me and my requirements for a tent.
