3. A seatpost rack with a drybag under 15lbs (when rack mounts are unavailable)
And is #3 taboo...
For me item #1 has worked well.
For item #2, I was put off by the weight and price of the Carridice and the price of the Relevate. I also find them to be less expandable for times when you need to carry extra stuff for small portions of the tour. That last could be rectified by using a backpack.
For item #3, I almost went that route, but decided it was probably a bad idea. You can always figure out better ways of mounting a rack even on a carbon frame. If you have cantilever or V brakes I like the little Nashbar or Sunlite Gold Tec racks that mount on the canti bosses. They are intended for the front but easily adapt to the back. At 10 ounce they are very light and adequately sturdy. I used mine last trip and it worked fine. This rack will easily fit a 20 liter eVac Dry Bag mounted crosswise. The bag can be rolled down to 10-15 liters and allow for some expand-ability.
