Philippe, my home course has a few holes that are quite similar to what you describe. I played on Saturday and hit the ball quite well off the tee, but hit only 2 total fairways. By my recollection, I was less than a yard off the edge of a fairway 8 other times. On those holes, I definitely felt less confident in my ability to control my distance on my approach.
I think a similar situation would unfold to what was described at the U.S. Open at Winged Foot: at a certain point, fairways become so narrow that accurate drivers cannot build an advantage over long and wild ones because everyone's fairways-hit percentage goes down significantly, together. It seems that a similar phenomenon might take place in your example.
