I have been using Marmot EOS 1P with Vargo Ti stakes.
And I don't use the drysack that the tent came with. I pack the tent relatively flat so that I can fit it in my frame bag.
IMO, there are two ways to tour. You pack everything you need before you go, or pack light and go buy stuff there
if you need something. Many people imagine going through mountain roads or desert when going oversea bike tour, however, reality is, you will travel on 99% road(paved or not) that connect other city or town. And people will be there and will have shops that you can get stuff from. Once I got a camera from small town in Asia because I dropped my camera and it broke. Was it a good camera? No. Did it work? Yes. I actually like that camera because it was cheap. The camera that broke cost me $600 vs. $150 that I got from Asia.
I recommend try not to save money on the bike and sleep system, but don't get too stressed on pack everything.
