Honestly, IMO, I think this is all getting to be a bit too much. Why do so many people love this game? Because, for the most part, it's you against NATURE.....against the elements, the lay of the land, the grass type, the turf and soil conditions.
I think it only makes the game more CHALLANGING for all, especially the pros, when the game has to be played by FEEL, and not by reading some number and having it register as "fast, slow, firm, soft, receptive, etc. etc." without even having to walk on to a single green.
Won't trying to make all the greens as perfectly consistant in terms of speed and firmness only allow the professionals to be better able to judge EXACTLY how their ball will react on the putting surface? The professionals of today are amazing athletes with exceptional technology. I think the diversity, the INCONSISTANCY, and the sheer feeling of NOT KNOWING how fast each and every green will run or how receptive it will be to a particular shot is the last defense this game has against golfers who can throw darts at any pin inside of 150 yards.
The farther we push grass towards NUMBERS, as opposed to what is actually best for the plant itself and it's role in the game, the more we are dooming ourselves (and I speak most specifically for me, as a superintendent) to struggle and inevitably fail.
