These are bicycles, not F1 cars and I'm hardly going to bin a 2k frame just because it has a little crack. Fibre Lyte do excellent work and are reasonably prices to boot.
We normally bin anything damaged but that's not to say you shouldn't be able to fix as you can view it similar to fibreglass which repairs incredibly well and with the same strength.
I would guess that one issue you would have would be matching the resins ?
CBS are good http://www.carboncyclerepairs.co.uk/index.html
Turn around time is pretty quick and also offer a paint service too.
