I hope I do not come across as overly critical. This is a style, just one that I am not fond of. However, I can certainly see why an extreme style such as this attracts many fans and ardent ones at that. No doubt the playability and interest is improved upon with these changes. I'm sure the playing public will enjoy the improvements.
How is the course to be maintained? How was it presented in the past? Is playability paramount or lush/green turf? Soft or firm?
This use of bunkering at Pasatiempo once again demonstrates MacKenzie's tendency to over-bunker and frame greens, especially the rear. I take it this is a US style that he did not use in the UK. Is that so? If so, why did he design so differently? Did he feel the American audience needed a helping hand or that this appealed to our sensibilities more?
The problem with so many bunkers with complicated outlines is that they simply don't look like they were naturally made. The original look was probably much more in harmony with the surrounds. Perhaps because they are new this overt appearance will fade in time. Is that the intent? Will there be a measure of natural evolution or is this the look that will be held?
To me, the long narrow finger in the right front bunker below detracts from an otherwise attractive bunker and does not fit in very well with the other bunker looks. The top left corner of that bunker somewhat mimics a larger feature in the bunker behind. Is this coincidental and is it original/intentional?
I don't know if this bunker is original or not, but it is unusual in how shallow it is and how it follows the exact contour of the slope rather than being cut in at all.
I also observe that there are many flowing curves and lines to these bunkers but that a great many also have portions with rather straight lines. Is this typical of MacKenzie or a more modern interpretation?
