Fast but uncomfy - fit critique required (pics)

With thanks in advance.
I´m trying to tweak this position a bit, and am thinking that the best way would be to fabricate a fast forward seat post. I feel I´m right on the tip of the saddle and it´s a bit too uncomfy for any length of time.
I am trying to avoid ´wimping out´ and sitting higher up.
Last TT was at a 44.8 km/h average so speed-wise things are good, I just want to find a bit more comfort.
Cheers all!
Simon
