Woods vs. Irons

[3Putt]

Is there a fundamental difference between a stroke made with an iron vs one with a wood?

My motivation for asking this question is that I have the wood/hybrid game of a solid single digit handicapper. And the iron game of a nervous 25 handicapper.

What struck me a few weeks back was TV commentary at The Players that David Toms was a "sweeper" of the ball. Is that comment based on anything real/demonstrable or just convenient colour commentary? I have always seen myself as a "sweeper" - rarely break a tee, generally shallow divots, etc. I'd like to explore if this characterization is legitimate or if I am simply rationalizing what is really a faulty pattern or execution with my irons.

I'd enjoy a discussion on this topic. Thanks.
