Mike,
Don't know about the ODG other than Ross and CBM had domed fw from time to time....or hogback.
But, I agree. I tend to use them for the 300+ landing zones. While I might add a small bunker out there occaisionally, it doesn't often seem that its worth the money for the .03% of golfers who can bomb it.
There are quite a variety of splines - straight hogback, angled, and even full tilt cross slope that might take the ball in the rough. There are also good old fashion fw chocolate drops (somewhat melted for mowing.....) Hitting it 300 plus probably isn't a good enough reason to truly F up someone, (kind of like making $300K doesn't make it right for the govt. to tax it above 50%....but thats another story) So, a slightly worse angle, or maybe even a slightly more uneven lie seems about right for the slight inaccuracy.
Got to ask WTF? Not one hint of Merion in this question........smile. Or, at least I hope Merion doesn't have a spline fw or we will be off to the races figuring if CBM did it based on the hogback at NGLA>>>
