387 is my longest on record, came on St Andrews. 402 was my real longest but it went through the fairway, over the green, through the fringe and into the first cut of rough. Supertri, little backspin 30MPH tailwind. The real long balls need the first bounce to be huge, and there are certain areas like STA #5 that have areas to hit to where you get an extra 40yds.
