I started putting ribs in my grips a couple years ago, but never got around to ribbing my newest clubs with the construction of my new man cave taking up the majority of my free time. Hopefully I’ll get to that before next spring. On a side note, using the Harrington grip shows a gain of 4-5 yards on my sim. Using the stack and tilt method along with the Harrington grip showed a gain of 15-20 yards on my 8-iron occasionally, but that stack and tilt will definitely take some trial and error on my part. That is if my back can take it. It seemed like it put my body in a better position at impact, something I’ve not felt in years. It seems when I injured my back years ago I made adjustments that eased the pressure on my back, but caused me to lose massive distance over time. Lots of time on the sim and inversion table this winter may pay off next season......
