For the longest time I only would play Callaway or Mizuno. I had bias from fitters, local stores, and previous use.
I was not a huge fan of taylormade or ping just for personal reasons.
hiwever as I have taken golf more serious and entered local competitions I got fit again and ironically got fit into the new p790 irons, stealth 2 3 wood, and a ping 5 wood. I still can’t get rid of my callaway driver but regret not giving king or TM the chance before now.
putter wise very biased to use scotty or odyssey.
bad bias - have heard nightmare stories on PXG so tend to avoid.
