As someone who has played both Pebble and Pac Dunes, I wouldn't even know where to start in comparing the 6th and 7th holes at each course.
On one hand you have a short downhill par 3 and a gettable par 5. On the other a short but devilish par 4 followed by a longer par that plays as the No. 1 handicap on the course. In my book, they are all great holes, each offering a different type of challenge and requiring different types of shots.
Perhaps this, in a microcosm, shows exactly why the hole by hole match play scenario misses something.
