Really Good Question:
Answering in GS Dave's format:
Driver: Titleist 917D3 (always accepting auditions for this fickle spot)
FW: Titleist 917F2 18 Degree-This could be the one, no chance this is going anywhere anytime soon.
Hybrid: Titleist 816 H1 21 and 23 degree Same as F2 FW, unless the 818 hybrids are much better somehow.
Irons: Mizuno JPX900 Hot Metal, they are in the bag for testing and doing well, but will have to hold off a challenge from the Titleist 718 AP3's and Mizuno MMC/FLi Hi combo when they come out.
Wedges: Vokey SM6 They aer the longest running clubs in the bag now. beginning of 2016 season. Like others have said, if they lose out it will be to the new Vokeys in 2018
Putter: SC X7M-Right there with Vokey wedges, in the bag since beginning of 2016. But will get a challenge from Toulon Indianapolis
Overall very happy with 95% of my bag right now.
