Another top notch course in the Dornoch area would be help the smaller venues imo. I am not convinced Dornoch will benefit though as it doesn't need more visitors!
I am not sure what authentic Scottish feel is, but I think you will not find it a new high end course.
Sean, when you say that you are "not convinced Dornoch will benefit", are you referring to the town or the golf club?
True, RDGC does not need more visitor rounds nor does it need any "help" attracting outside interest. However, as cited previously, following the opening of Castle Stuart, the town of Dornoch saw a net LOSS in visitor room/hotel nights. That trickles down to everyone: restaurants, shops, pubs, etc.
It became clear that golf tourism was treating Dornoch in a very transient manner that benefited RDGC, but bypassed the town. It is also well-documented that the developers of Coul Links first came to RDGC with a proposal.
Part of the appeal of the developer's proposal behind Coul is that it could add the need for 100 more hotel beds in the area. Is that good or bad? Well, it depends on your perspective. If the town of Dornoch became a golf tourism "hub" in the Highlands, instead of a "spoke" of Inverness, that could lead to a net benefit for Brora, Golspie and the town.
