Why the Difference in Length Between a Thriver Versus a 3 Wood?

One of the very good questions I receive is in regards to the suggested playing length of the Acer XF Thriver versus that of a 3 wood.  Both the XF Thriver and the matching XF 3 wood have a spec weight of 210g but the recommended playing length is a 1” difference.  This begs to question, why?

For those of you that may not be aware of what a Thriver is combine the terms Three Wood + Driver and you get Thriver.  A 3 wood is more lofted and this cuts down on side spin, plus is shorter to enable one to have more control.  On the other hand, a driver is approximately three times the size of a 3 wood which makes it much more forgiving on off-center shots.  Plus you have the large confidence building, thin face that produces maximum distance.  The Thriver is a full 10g more than a normal driver to allow for a shorter, more controllable length that now has the proper amount of weight in the player’s hands. The Acer XF Thriver has the best of both worlds when it comes to these two heads.

Let me set the record straight and provide advice to both clubmakers and consumers deciding on what length would fit them or their customers better. Part of the explanation of the length discrepancy can be found in in the clubs respective sizes.  The face profile of a driver (or our Thriver) is much deeper or taller than a 3 wood.  The reasoning is it is designed to hit a ball off of an elevated tee.  In contrast, a fairway wood is shallow as it needs to hit the ball primarily off of the fairway or out of the rough.  As such, the deeper face will possess a higher center of gravity (CG) or as we can see from the diagram shift the CG closer to the grip or the player’s hands.

Another difference is even though the length is the same the bottom of bore to ground line measure is ¾” higher off the ground than the matching 3 wood.  This is quite normal with today’s drivers, but does mean that the cut shaft is shorter and doesn’t weight as much as the same shaft in a 3 wood.  This means with the same shaft, grip and overall length the Thriver will have a reduced swingweight by nearly 2.5 points.

But didn’t you just say that there is a 1” difference in length and a 2.5 or 3 swingweight only justifies a ½” difference in length?  Yes, that is true, by making the Thriver ½” longer than the #3 wood using the same shaft and grip the swingweight will be the same. At 1” longer then the swingweight would be higher.

Consider this, the extra swingweight will create a more head heavy feel and less likely for the player to get quick off of the tee and have a more even tempo.  One other phenomenon that occurs is many golfers use a heavier shaft in their fairway woods than the driver for control.  For instance they may use a 65g shaft in their driver and 75g shaft for their fairway wood(s).  This will also have a bearing as the heavier shaft will increase the swingweight so the difference between the Thriver and the 3 wood might not be as much.

However, if you are using the shaft weight shaft in the Thriver and fairway and you need added control off of the tee, you can certainly go shorter and make the Thriver ½” longer than the #3 wood or what we call as ½” under standard and still have a well-balanced tee club.

It is hard to argue the success of our Thriver (both this generation and the previous Acer XDS Insider version) as they have received the highest rated reviews by your peers.  So whether you want to go 1” longer or only ½” long than a 3-wood, don’t make the mistake of ordering or assembling them the same length just because they are the same weight.

    Hello. I am interested in getting an XF thriver with an SK fiber tour trac 80 in stiff at 43.5 inches. What would the swing weight be for the club. Also, would it be possible to get an XF thriver head that is square?

    You would be looking at @ D0. Sorry, we do not hand pick for face angle.
