If you want to maintain the same feel in the HDI 2 and 3 as your irons, obviously it makes since to go with the Tour X Xcaliber. The Kuro Kage are about 20 grams lighter with slightly higher torque, but have the same trajectory. The lighter weight could be helpful in these longer irons and the slightly higher torque will make them feel less firm, but that may not be what you are looking for. Either option is a quality product, it’s kind of up to you as to what feel you are looking for in a Hybrid Driving Iron. Most players that I have worked with, in the driving irons, want a shaft that is the same or slightly lighter than in their irons, and one that will take a little less effort to get the ball airborne. You might actually look at the Xcal Tour X 85 as an option. 10 grams lighter with a mid trajectory, but built with the same technology and materials as your Tour X 95 irons.
Thank you for mentioning the 85 gram shaft option which I was thinking would be a better weight transition between the irons to the woods.
I want to thank the Maltby crew for continuing to produce the quality gear that you do. After a break from golf I returned with an OEM set of irons that while they played well the tinkerer in me wanted to return to Golfworks products. As I have found in the past your products outplay and out forgive the top OEM irons out each year. I hope that you are given the budget to continue the work it takes to stay on that cutting edge. DBM’S RULE!!!
