Went with a couple of mates last night to a trackman SIM to gather some data around club-head speed as we're looking to increase this by the end of the year
Also verified my PW, 8i and 6i yardages were what I'd expect out on the course.
I was doing similar with my driver last night, just a 45 min session with my coach on trackman - looking at launch angle and spin (and technique) I’ve increased the loft on my Ping G400 from 10.5 to 12 degrees and am getting great results (on the trackman and ball on the fairway more) ?
