Niall,
re: Bunker style. It is very saddening that many of the bigger names all seem to be doing the same [box standard] style of frilly, jagged edged bunkering. C&C, Doak, M&E all look the same to me. You talk about evolution and the chances of the architect's style evolving but it seems to me that they all started at different points and have ended up at the same place. Doak's Common Ground appears to be the only exception in recent years. If the style is to change it will probably be down to the greenkeepers rather than the GCA.
Ally,
I agree that one company getting so much work is not good. There are plenty of other good people out there though I think Trump's course was a nail in the coffin for Martin Hawtree where what he produced was mediocre for the site.
