I love the smiley bridge pin formation, too. Have any idea why Taylor switched it?
The smiley bridge pin formation was switched in 1998 or 1999, I believe. Taylor's reasoning, as a I recall was:
1. easier to mass produce a straight line of bridge pin holes, and
2. no appreciable advantage (soundwise) of the smiley bridge pin formation
...but it does look cool! I'm glad that I have that feature on my '95 and '97 below:
