This might deserve a separate thread,
but
Given the desire to test the players with firm greens-which isn't always attainable due to weather or wanting actual puttable grass on the greens(I'll leave the fast part for another debate)..
What about a slightly higher cut for the fairways (back to the stone ages of the 70's or 80's) that creates slightly less spin, making approaches more difficult to spin exactly and put judgement of lie, sidehill lies(due to ore friction keeping ball from finding flat spot)
This would slighly reduce roll on tee shots(they could still be firm and bouncy)
and place more of a premium on angles given less ability to spin it from anywhere.
and make players use height, not just spin, when needed to stop the ball.
Additionally, less irrigation would be required to keep them healthy, increasing the chances they would be firmer.
Would certainly make the game far more fun for average players as well-allowing them to actually hit some decent shots around the green with chilichunkitis or always putting.
While some would argue the slightly reduced spin increases luck in the fairway, I would argue it requires more skill to evaluate lie and hit a creative, controlled shot, rather than a dialed in Trackman(Plus or minus air density)number-and makes a player think about angle of approach if less spin attainable.
Somehow Hogan, Nelson, Snead Nicklaus, Trevino etc. managed to control distance in such conditions.
It's certainly no less "fair" than killing and turning a green into a bumpy plinkofest to "protect par" where sheer luck of the draw is involved.
Of course they could apply the same treatment to the greens,to allow healthy firmer turf, and use more interesting pins in slopier spots..to create a wider variety of speed on uphill, sidehill and downhill putts and approaches.
Heavy sigh..
I will say I enjoy the slopes still on the greens and fairways at Pebble and they are far greater than most courses with the greens running at a good speed for the slopes.
But they are not reflective your normal Tour or high end course.
