@iacas, thanks for your detailed comments. i know sometimes tone can be difficult to discern online and as a new member of this community i'm still getting used to the style of communication here. i apologize if you feel i put words in your mouth (totally unintentional) and i don't harbor any ill will about what i considered snarky/sarcastic.
i think it's difficult to compare this picture of DJ because he's wearing layers and a collar. additionally, the fact that the picture of mike on the left is intentionally exaggerated limits its usefulness in my opinion.
i just searched for "dustin johnson down the line slow motion" in youtube and here are a couple of pictures from the first few videos that showed up.
here's one of DJ with an iron in his hand and no layers from the open in 2017. to my untrained eye his spine seems to be in a much more neutral position. there's plenty of space between his chin and chest and it looks like there's a little bit of anterior pelvic tilt. (please forgive my crappy dots 🙂
and here's a picture of DJ with driver in his hand from a video that was uploaded about a year ago though i don't know when it was filmed:
further, this is what DJ has to say (in his own words) about his posture in an interview with golf.com from 2016:
so to answer your question i would say DJ's posture looks (to me) more like the picture of mike on the left but with less anterior pelvic tilt and less extension in the cervical spine. and based on what he has to say about his posture he doesn't want to set up like mike in the picture on the right.
In the last 15 years, a lot of work has been done on fairway wood heads. This includes moving around the center of gravity (see diagram of RBZ Stage 2 FW). 1. Higher and more forward leads to lower spin, more penetrating shot. This works best for golfers with high clubhead speed. 2. Lower and more rearward leads to higher spin and higher launch, which can maximize distance for the average golfer.
In 2006, Tour Edge launched the Exotics line of FW. Exotics
used titanium cup-face, and steel maraging (removes dead weight from hitting area) to develop some very hot FWs and hybrids. This year's EXS model uses a new high-density carbon steel alloy
Callaway, Cobra, Mizuno and Ping likewise developed FWs with a variety of head options.
Of course, the FW works best if you fit it with a shaft that matches your swing.
Go to a demo day, and do a side-by-side with your 3W and others. And, if you carry a single FW, also try 4Ws. Many players - including some big hitters - get more out of a 4W than a 3W. This depends in part on how you come into the ball.
Here also is a link to the 2018 MyGolfSpy article rating 3 woods for 2018. Given it's 2019 now I'm sure any improved technology between now and 2018 is almost immeasurable, although I'm sure you'll find marketing pitches that contradict that.
2018 MOST WANTED FAIRWAY WOOD
24 Fariway Woods, 20 Testers, the largest unbiased head-to-head 3 wood test in the world.
Short Story is #1 = Exoitics CBx, #2 = Callaway Rogue, #3 = Callaway Rogue SubZero, and there are many others included.
I always take these types of things with a grain of salt. "The Best" tend to come from some method of aggregating the data of the test results and the only thing I can be sure of is that my results will almost surely aggregate differently. Then of course there is always the argument of how much a particular company might have "donated" to this test group and how that might influence the results. Also I believe the right shaft is a big variable in anyone's swing but I could not find what shaft manufacturer was used in the testing so I have to assume they used what ever the stock shaft was that came in the club (noting that sometimes there can be different shafts used within the same year by the same club manufacturer).
Still this information is very interesting, and although it does not answer your question how much better they are than your 2008 gamer, you might take your gamer and try some of these clubs in the list to see how they compare.
