Between the loot, usually 4-5 different brands.
I carry driver, 3 wood, hybrids, iron set, wedge and a putter. Sometimes the driver and the 3 wood are the same brand, sometimes the irons and the wedges are the same brands, depending on which one is in the bag and the condition of the golf course.
In recent years, I added the hybrids to the bag.... in the old days maybe just 3 kinds of brands in the bag, woods, irons and the putter.
