CX frames have relaxed geometry (slack head tube angle) and with long chain stays, this gives a long wheelbase and so they don't turn into corners very quickly. I would go for something like a Cannondale Synapse Disc (either 105 or Ultegra). Not hydraulic brakes but it has rack and mudguard mounts. The 2014 models are going cheap right now.
Thanks for the suggestion but hydro only. The TCX seems to fit the criteria best for the price (remembering its not the end game frame).
For myself, at the end of next season I will be looking to get a run out 2015 Focus Cayo 3.0 with Ultegra and R785 hyrdo discs Don't know what I will do with my Giant Defy advanced 1 when that day comes (it will be pretty much redundant).
