6 different brands I think. 2 Pings, driver and 58 deg. wedge. 2 Orlimars left from a full set, 3 wood and 3 hybrid, Palm Springs putter, Wilson irons and a house brand 54 degree wedge from Golf Galaxy with another house brand 2 hybrid from ahh... that place that closed a couple years ago near the mall.
I've averaged about 5 different brands in my bag over the last 30 years but after adding the Epic Forged 4 iron recently, I'm down to just Callaway/Odyssey and Srixon/Cleveland.
