A big issue with no first cut are tilted fairways and their runoffs.
When we were at Indianwood, balls would routinely trickle off the canted fairways and stop next to the rough.
Thus, the rough was unusually heavy behind the ball, as it was sitting down.
Sorry, but not appropriate.
Perhaps another way to look at the debate is to compare fairways to greens. The collar separates the putting surface from areas of rough. Thus the first cut should also be viewed that way....as a transition area.
As a way of compromise, clubs can mow the first cut 'into' the fairway. In other words, instead of a fairway width of 32 yards and a 1 yard wide first cut on each side, why not a 30 yard fwy and a 1 yd cut on each side. Thus, the fairway is actually narrower, yet those trickles receive a more fitting result.
