I hadn't really thought of a rough collar stopping the ability to "hide" the bunker links-style, as Frank mentions - this is something that requires a pretty flat hole (if there is movement in the land, you could just as easily hide the bunker behind a hill if this is your intent)
Tom's point makes sense though. Dunno if there is a good way around this, and its too bad because I really do like centerline hazards as a way to get people away from the usual "aim down the middle" and start thinking strategically a bit. Maybe I'm dreaming, but I think if you expose people to a bit of strategy, they might start thinking about strategy elsewhere over time. Get enough people thinking about it and the better courses (well, the courses we in GCA consider better
) will get more love, and "championship"/penal/purty courses will not be overrated quite so much.
If they're going to maintain the bunkers with rough anyway, maybe just stick a grass bunker out there instead of a sand bunker? If its small and not SO long that you have to stomp around for 5 minutes hoping to step on your ball to find it, but have a combination of grass length and sloped faces that make it something testing even for good players. I know a lot of people here will have an immediate revulsion to this idea, but this is really a fairer test - poor players are a disaster in the sand but can at least chop the ball out of the long grass (they have plenty of experience in rough, after all!) Unless you have a true pot bunker, which is hard to build in most places in the US, good players don't really care about bunkers if they're hitting a short iron. But hitting off a 30* sidehill lie out of 7" grass.....yeah, that's going to concern them!
