And to give you hope for continuing improvement - we're the same size and my CdA is under 0.25 in a tri (lower again for TT). I think your legs are a touch longer which will count against you. For the moment my aim is to see what effect getting skinny will have on drag (and running) and then revisit my position to see if further alterations (along with finally getting a Pos4 that works) can get me to my lifetime goal.
