It seems that most instructional articles suggest that as the length of the golf club increases from 9 to 2, 3, etc. the stance should widen. I too widen my stance but ever so slightly. My result is a steeper angle than widening the stance but my result is a higher ball flight than if i widen my stance. My stance never gets to shoulder width except with driver.
The longer shaft, as such, does not appear to me to necessitate a wider stance, especially with the irons which are all struck with a descending angle. I understand the driver off a tee requires a swing to make contact on a slight upward angle to achieve the elevation, low spin and maximize distance. But widening the stance with irons just seems like it puts an additional "different thing" into setup and tends to change the swing plane on every iron.
I suppose the answer is......."if it works for you, have at it laddie."
Question: Anyone else experiment with this? And, results?
