Carbon seat post - creaking noise?

Anyone have problems with a carbon seatpost making creaking noises? I ride a Felt S22 (2005) and have the Felt seatpost with a Terry Butterfly saddle. The creaking only occurs when I am on the back of the saddle sitting up to climb. A few creaks here and there when I’m in the aerobars, but not too bad.

Any help for this?

Hmm… You sure it’s the seatpost creaking and not the saddle?

Nope, I’m not positive its the seat post. What’s the best way to determine whether its the seat post or the saddle? Put on a different saddle I guess?
