@Therty I spend a ton of time on a simulator and seeing the effects of a high VCOG iron in real time is tough to notice. What I have seen in real-time is where contact is made and it’s huge effect on spin. High and Low on the face.
Right now I’m playing a nostalgic for me set of irons with a very high vcog. The playing surface is new at the simulator and will allow a club head to really sink and hit a marginally fat shot. It will still feel good but will go nowhere, spin too much and fall way short. Ball Speed was way down as well.. A thin or bladed shot is far less penal as it’s still going to nearly go the intended distance with no spin but it’s 10′ off the ground. But in this case ball speed drops far less and at times does not drop at all. So the high Vcog did nothing to help in this case.
Proper spin or higher spin is very dependent on striking the ball well. High on the face is spinny but does not go a consistent distance. A guy who thins a shot with less spin will have a lot more consistent results, poor yes but far more consistent. I was so frustrated on this new surface till I put some impact tape on the face. Once I realized how fat contact was i was able to adjust. Sawpping in a more playable design was not showing me a big difference unless they had a wide sole or a much longer blade length. Both were keeping the iron from ‘sinking’ into this new turf. This was allowing better contact, and results.. but still I was seeing poor consistency due to higher than ideal strikes. But the more playable design shows how it can ‘help’ poor technique
I also test a ton of different shafts with identical heads and here is another area that will greatly influence spin rates.
I may be stating the obvious but seeing spin numbers and ball speed immediately being posted is a vital tool. Hope this makes sense.
