Kyle,
I am not suggesting that you are "wrong" and I am "right" - but I agree with Matt generally.
Most "tough" courses will be tougher for a 5 handicap than a scratch golfer because of ball control.
There is a reason that most scratch players play from the back tees while most 5 handicaps are better suited to the tees one up. In my experience, the scratch player is simply more consistent off the tee and rarely gets penalized with the driver.
Even shorter hitting scratch golfers usually have the ball striking skills to play from the tips, drive it 250 down the middle, and work the mid to long irons like surgeons.
I know this is not always the case - you are absolutely correct that this is not a black and white issue and cannot be oversimplified.
Jeff,
I was trying to focus my post on the specific question - which course distinguishes a scratch from a five - for me that does not have anything to do with strokes given in a match - just which courses really separate the sticks from the good players.
Yes, I agree, slope on its own is probably not a good example. Any element of a course that puts more weight into ball control will showcase the superior skills of most scratch golfers vs a 5 hcp. Whether that be the elements, tightly tree lined fairways, or whatever.
Obviously there are situations where a straight and steady 5 hcp with an okay short game and only okay putting has a chance to outperform an erratic off the tee short game master. But let's be honest, most guys on tour are long off the tee, with pretty good ball control - Tiger and Phil can be exceptions which makes them so exciting to watch.
