I once argued (politely) with Tommy N here about cross bunkers. I agree with Lyne that they are conceptually not as strong as the angle bunkers combined with a zig zag fw. I would argue that the 90 degree cross bunker would ever look natural or part of an artistic composition, unless there were some pretty strong cotours where it fit.
The best use of cross bunkers I have seen in modern times is John Fought's use of them in the second shot landing areas of par 5's. Not much different than Pates use on the par 4 above, but it seems like taking the risk to get within 100 yards, or having to lay back to 160 would be a good strategic decision on a par 5. And, if some can clear it and reach the green, that's okay too.
They would take some serious consideration in how far along the centerline these bunkers extend - IMHO they need to be well short of "Hell's half acre" for average play reasons, but perhaps thicker than a Raynor strip bunker. Otherwise, the range of distances they challenge is effectively too limited. If on a par 5, I could see one combined with a narrrow tee shot landing area, flanked with hazards. If you miss the fw, then you have real trouble clearing the cross hazard and it becomes a true 3 shot hole.
