Here's a hole by hole for fairway width and strategy. I'd rather everyone go out and discover for themselves, but here's my thoughts on the place.
1- 70 yards wide but plays 50ish due to angle of the tee shot. For long hitters it is risk/reward as a drive down the right opens up long approaches into the left to right sloping green, but in order to get this preferred angle you must flirt with the hazard down the right off the tee.
2- As mentioned already, the left-side plateau (30 yds wide and bordered by OB left) is preferred for most hole locations as it opens up the view of the green as well as allowing the golfer to not approach with as much of a downhill landing area on the approach. Back right hole location I prefer approaching from the far right of the fairway personally due to the knob in the middle of that green, but that is open for debate.
3- More obvious, plenty of choice, even for those who are trying to drive the green. Bunkers "pinch" the fairway to 30 yds on the right and 25 on the left, although laying up to the right distance will allow for more room. This hole calls for more in strategic decision-making than execution.
5- 50 yards wide. Generous but I doubt more than 80% of golfers still manage to find the fairway. Any fewer and things may slow down here as there is a wash to carry for the layup. Remembering that wind can blow both ways at Rustic and that this is a 3-shot par 5 for 95%+ of golfers this tee shot is more of a break. Still slightly angled and disorienting so that the golfer does not stand on that tee with total confidence.
7- 50 yards wide but if a golfer is more precise they can set themselves up with an advantage to those who blindly aim for the fairway. Rumples in the fairway can leave some interesting lies and can be cleared if the golf hits their tee shot farther down the fairway or closer to the wash. Also as previously mentioned a nice option to drive across the wash also exists- a great recent improvement to the hole.
9- Another 50 yard wide fairway, although this is perhaps the least interesting one strategically on the course. I won't pretend there's something here when there's not, this hole is about the green. Still appropriate for a par 5 where you can let one fly.
10- 45 yards between the pot bunker and the large bunker left, but a wider fairway short of the pot bunker. It may seem insignificant, but just wait until you hit into that sucker, it will play into your mind on that tee from there on out! Challenging the pot bunker and OB right can allow the golfer to cut off some yardage and give the 50 yard long green a go, but it takes two precise shots to pull that off. Also I did not give the 10th green much shot in my first dozen plays at RC, but now think it's one of the best out there. Tremendous elevation change from front to back but subtle and maddening in nature.
11- 53 yards wide but plays narrower due to the angle (from the Black and Blue tees). Playing close to the hazard left allows for a much shorter approach and on a long uphill par 4 the advantage is important to have. They could cut the rough to fairway height between 11 and 12 and it would not be a detriment to the strategy imposed by the tee shot. A very clear risk/reward.
12- 70 yards wide. Perhaps more of a mind game... It's a personal favorite and perhaps the closest comp is 18 at TOC in some ways. Distance and direction control is important so the golfer can leave the desired angle/yardage depending on pin position. Long hitters can give it a go and downwind irons can run through the fairway- a place where you don't want to approach some pins from.
13- A 60 yard wide landing zone with the central bunker leaving 30 yards of fairway on the left and 20 yards on the right. Keep your ball between the bunker and OB right (30 yards wide including rough) and the green may be within reach. At the very least your reward is a shorter layup that won't have to deal with the flanking fairway bunkers as much, allowing the golfer to choose the correct side of the fairway for the day's hole location.
14- A true cape hole drive. The fairway can be 100+ yards wide depending on angle and distance of tee shot, but you must pick your line correctly. You can probably figure out a lot more in person than I could describe for this one.
16- Probably the second least strategic hole to #9. Fairway is under 50 yards wide and with trouble on both sides it's one you have to hit. For the most downhill tee shot on the course in the prevailing wind, I don't know of many golfers who don't think this is a demanding enough tee shot. The approach has Pinehurst-esque elements and can be played in multiple ways- definitely a second shot golf hole, assuming you've executed on the first.
18- No more than 40 yards wide unless you can clear the right fairway bunker, 18 has always seemed a demanding drive to me. Carrying the right fairway bunker is fool's gold anyway as there's only about 5 more yards of width beyond (I believe some width was lost in the flood). In any case, a ball that hugs the right side of the fairway will give the golfer a clearer view of the green on the approach.
Just one guy's thoughts after dozens of plays. Outside of 9 & 16 there is very definitely a position A on every fairway. Missing that spot and still being in the fairway makes for a tougher, but still do-able shot. Recovery is maybe the most enjoyable element of golf, so having that opportunity so frequently makes Rustic fun time and again on repeat plays.
