As far as weight is concerned, think about how much weight your body puts on the seatpost. An additional 10 pounds or so is not going to break it. All attachments are velcro and nylon straps, which help absorb any shock. The only issue with CF is clamping something to it, which puts all the stresses in a small area. Not generally an issue with bikepacking bags, but a seatpost rack on a CF seatpost or a standard rack clamped to CF seatstays is generally not advisable.
I'm just thinking of the flexy seatpost that comes on the CDale Synapse. You can already (by design) feel it flex in certain circumstances, I'm just wondering if a bikepack would exaggerate it. I recently watched Inspired to Ride and those guys and gals mostly had the same setup, albeit even lighter than yours (bivy sacks instead of tents, and aero bars with sleeping pad wedged between the bars, focused more on speed than carrying comforts). Seems like a great setup for touring on a road bike.
I'm amused by how much corrado feels he has to voice his disapproval of the CF rack on multiple pages.
