Carbon Creak: Too tight or too loose?

I've got a good creak (nearly a snapping sound) coming out of my seatpost area when going over bumps (while seated) or shifting my weight. I've got carbon assembly paste between the frame and seatpost (both carbon) and a ti rail saddle.

Any guesses?

Nope, I grease all of my bolts, so a torque wrench is pointless.

What?

Can you make the sound when you grab and stress the seat? How about when shifting your weight but stationary? Andy.

Most torque specs are for dry threads. A lot of torque specs are max torque. My seat post says 5-7 Nm max torque for dry threads. The "right" torque is 5-7 Nm. Is 5 Nm more right than 7 Nm?

What should I torque it to with Finish Line Teflon Grease?

Yes, I can make the sound off the bike with my hands as well as stationary without pedaling.

Not sure if you greased the rails too? This has often been the source of saddle creaks for me and a greasing of the rails has always fixed.
