Matt:
The problem, as I see it, with your central argument is that you paint with too broad of a brushstroke.
You lump together all of the changes made at Augusta, condemn them in unison, and long for the course that existed before the changes. This, despite a fair mountain of evidence -- cited on this DG and in other forums -- that changes in club and ball technology have clearly led to measurable increases in distance (as well as straighter ball flights) in the last 20 years. You also seem to ignore statistics on this thread, regarding e.g., eagles per tournament, without any corresponding statistics on your end to augment your argument. (You ask us to go find them -- see reply #114 -- without doing the work yourself to buttress your case.)
I know a lot less about Augusta than you do, but I can't help but think Jones and Co. didn't design, in particular, holes 13 and 15 to make golfers think about what kind of shot they wanted to play off the tee, and what shot they would play for the second based on the outcome of their tee shot. The extraordinary use of the terrain on those two holes, by any rationale assessment, would lead one to conclude that Jones envisioned those holes being played in a variety of ways, for both different skill sets of golfers (Johnson vs. Woods) and different outcomes of particular shots. Lengthening those holes, it seems, is a defendable approach to maintaining the integrity of how Jones thought those holes ought to be played, I'd argue.
You harp on the second cut of rough, and excess tree planting, and in some respects I can see your point. But as folks like Pat Mucci (who's among DG posters has actually played the place post-changes, I believe) point it, there is still ample width among the fairways, and perhaps its not a bad thing at the Masters to have golfers pause on the tee before pulling their driver on every hole (and the TOC reference you keeping bringing up is, I'd suggest, something of a false one. TOC in Open set-up/conditions has never been a all-driver, all-the-time course, pre- or post-technology boom. Nicklaus never played 12 with a driver off the tee, and rarely played 16 that way. Tiger regularly attacks TOC with a variety of clubs off the tee -- sometimes driver on 12 to blast OVER the green and play back, sometimes fairway wood/2-iron on 14 off the tee for better placement for his 2nd into the green.)
Finally, I have yet to see you or anyone else address the benign nature that is emerging in recent years of the course's most famous hole, #12. It's now the easiest par 3 on the course, and is little more than a wedge/9-iron at the Masters for most players. Think that's what Jones envisioned for that hole?
