I have played both. Dixie Cup last year, 5th Major this year.
BH 4. I hit driver, left rough, hacked it out and it went too far down thru the fairway, hacked that out and either made 5 or 6.
DR 4. Between our matches I played it 3 times or so. I had 7 iron in once on my second shot and still made only par. Don't think I ever made birdie. My point is I think it's a devilish par 5 or 4.5 full of strategy. Whereas, BH 4 is a brute. I thought BH was THE most difficult driving course I have ever played as it was narrow effectively off the tee due to the mucho thick second cut. Or atleast there was a severe penalty for missing the fairway on any hole. I played 72 holes at Ballyneal and DR with the same ball. Can't do that at BH.
But, I like both courses.
I say 4 is no blood. Next.
