Compared to the D300 driver, the Wilson Staff D300 fairway has undergone a more radical makeover.
The footprint of the head has been made around 2mm deeper front to back and is 'pulled' a little more towards the toe section to draw the weight lower and further back.
It maybe does not look as smooth at address and there is not face/crown colour contrast, but on the plus side the face is more square than the rather closed Wilson Staff D200 fairway it replaces, so overall that's a positive.
The all back face uses a Carpenter Custom 455 Face Insert and is now also taller vertically with a more contoured leading edge which is all part of the increased aerodynamic story that Wilson are pushing with the D300.
This culminates in the Micro Vortex Generators that are a series of nodules in the crown that are there to disrupt the airflow over the head to keep it attached for longer, thereby reducing friction and making the head go faster.
This has been tried by other manufacturers who freely admit that it works in drivers, but as the head size gets smaller the effect also reduces. It probably doesn't hurt on the fairway, but I am not sure how much of a boost it actually gives.to the speed or the looks.
Investigating this further on SkyTrak, the numbers were same for club head speed against the previous D200, but with both being fixed hosel clubs, there were using different shafts so this is not categorical.
What it does show is the effect of the deeper head as the D300 fairway created more spin and a higher launch for a 6 yard higher peak height.
This resulted in similar carry but less roll so if you a prone to using fairways as approach clubs into greens then the D300 is more likely to stop quicker.
With a choice of three lofts for righties, the higher lofted 18° and 21° models could therefore be viable alternatives to hybrids if you are someone who doesn't get on with the smaller headed clubs, which the Wilson Staff D300 hybrid certainly is.
Other differences include the Matrix Speed Rulz A Type shaft in a red and black colour scheme to replace the UST Mamiya Elements Chrome of the D200.
The new shaft seems to have a firmer mid-section than the more uniform UST and that will be good for increasing speed for those who need it.
It also sounds better than the D200 and the feel is good so the Wilson Staff D300 is a solid, if maybe not spectacular fairway.
So why would you consider it? Provided you need the flight it delivers then it is probably because of the price. The D300 is one of the cheapest fairway woods from a major brand around and therefore you are getting a quality product at a competitive price.
