I like doing the Trifecta: 45+, 35+, and Pro-I-II once a year or so but only if the course is favorable and there's not too much down time in between events.

If promoters were smart, they would run their Masters race right before the Pro-1-2 to entice more doubles.
I can't understand when some events put the Masters race at 8am and the pro race at 4pm.
