This is copied over from the ". . .Aha moment. . ." thread, because I wanted to reference it for further growth.
<This is after a good lunch range session today (and also last night), where I only focused on irons. Hit 200 balls last night, and another 170 balls at lunch.>
I think I just had another "Aha" moment last week, when I switched to clubs that were way too stiff and heavy for me on the course.
My last lesson had me me get into a deeper stance and a 2:00-2:30 spine angle. This gives me a lot more freedom of movement. Of course, they said it would during my lesson, but it didn't click then mainly because I was not used to this deeper stance and needed to build up the strength to do get into it.
What the "Aha" moment is that I was able to swing these heavy solid steel rods with ease, and let the club propel the ball and cut through turf. I've been working hard to produce this feeling every stroke. I found that I can reproduce this feeling up to the 7 iron pretty reliably, less so with the 6 iron, getting a few good shots with the 5 an 4 irons, and very limited few with the 3. I can still hit them every time, but they make a clack sound rather than a poof type sound on contact.
However, this got me thinking a bit. All of my "good" shots up to the 5 iron were about the same ~30 yard height. I even swung my wedges (52 and 60 degree) the same way. Also, there is way more spin and height with no distance loss. Repeatability was much better.
I have always used these clubs at home against a net, but never really knew how far the shots would really go. Then just decided to take them out on the course for a round.
Still have a lot of work to do to be more reliable with this new found "ease of movement". After which, I'll be ready for the next lesson!
The main thing is that I seem to be getting used to the heavier clubs. Only time will tell, but it seems like they are, hopefully, not going to over-work my core muscles like they did on the course the other day.
