On the practicalities side I have discovered that Tubus do a rather nice lightweight titanium rack called the Airy. The price is pretty eye-watering though so I may have to make do with a cheaper and much heavier alloy rack.

Some component clarity
I think I am now settled on SRAM shifters, purely for the additional multi-shift capability (3 steps) over and above the Shimano (2 steps). Having crunched some numbers the cassette that best fits my needs is going to be 12-27 which will necessitate a medium/long cage on the rear mech. That compbination of 3-step shifts and reasonable ranged cassette should mean that if I get caught having to stop at traffic lights when I am on the big ring two full pumps will get me from a cruising gear down to something I can pull away in. Alternatively if it is stop-start round town I can just drop down onto the small ring and dance around the top end of the cassette.

Total now spent £759, claimed weight of parts purchased 2895g

Decisions
Ordering in some full carbon forks should be an easy decision as there are very few carbon v-brake forks available and fewer still that have carbon steerers.
A much harder choice is the one of groupsets. 2011 year 105 stuff is easily good enough but part of me says that if I am building myself a bike for the next 15 years shouldn't I spend a little extra on ultegra. Then my wallet kicks in and says that SRAM Rival is a very good system that is much cheaper, albeit lacking the double-downshift that the shimano kit has. Then considerations of longevity and ease of replacement push me back towards shimano kit.
If I can get some good FSA cranks second hand then that would push me towards the ultegra shifters.
