Just got a Floyd frame made with Columbus air tubing but the seat post is a little fubared anyone got a full aero post that will fit?

I have the same problem with my frame. In fact I am not even sure whether my seat post is an original Air one, it has been welded at the back where a previous owner must have tightened up the seat post bolt too much, causing it to puncture the post. Most info I could find regarding a replacement post come from here

Looks like a Shimano Dura Ace AX post with a shim works
