I don't know about RNK, but my opinion of TR is that it starts with quirk in that it is on a quarry site with many quirky things to deal with. Many of the quirky stuff was not overly manufactured, like the waste areas, and the sand cliff wall carry on 18, etc. The factor that what was done there, managed to work with the quirk, and isn't by that area standards and excessively expensive course due to excessive construction of quirk, makes it good quirk in my mind.
