On the 7th hole, why didn't he want you to hit your perfect full 9 iron shot?
Why did he want you to keep using the 3/4 type shot?
I do this a lot.
More control, better strike, better chance of hitting it correct distance is my thinking. If you have a 140 yard shot, and 140 yard max distance club, any mistrike comes up a good bit short. Plus swinging harder gives you more scope to lose control, in my experience.
Under 150/140 yards it is very rare for me to hit a full out shot into a green.
Plus, being on the coast, it is easier to keep it lower.
