Had my new 620 cbs a couple months and at first was really struggling with them (upgraded from 716 ap2) . But in fairness I’d not been playing great. So kicked myself up the rear end and got back to seeing my coach and in 5 weeks I’ve got my swing not far from where it should be, got more consistency and dispersion has been so much better that the ap2s. Shot -4 a couple weeks ago and now back down to scratch . So with all this in mind I went for a new fitting with a guy that works on tour and he discovered my irons are 12g lighter than they should be!! I am 5ft 9 and my set up requires them to be 1/2” shorter. So the point of my story I suppose is get properly fitted when getting some new clubs as it can be such a massive difference and also you’re never too good for lessons #teamtitleist
