I think perhaps this shot is very seldom used in professional golf because of the unpredictability of it, "use at own risk". I think the use of it on WGT is a lot more controlled for the user especially with the application of spin, kind of making it an "unfair" shot.
But I agree that this topic has pro's ad con's, arguments and counters. I have only ever seen it been used twice.
Personally when an approach shot darts 50 yards past the pin on the 5th hole at St Andrews, I strangely relish the chance, albeit a very small chance, of sinking a monster putt.
