Ian,
I have played the 16th before and after and would say that in terms of looks that the new hole is as asthetically pleasing. I also think that its now a better hole with more to consider on the approach shot with the burn running round to the right as you look at the green.
When I played there last year they had put in a lot of the new bunkering which was really noticeable on the 1st where it just looked like a line of bunkers running up each side of the fairway, not the most inspiring sight. I had heard that they were considering taking out some of the bunkers that they had put in but don't know if this is true.
