D2 swingweight because the weight of the components and the assembled length won't allow you to. Rather, and most importantly, fit the swingweight based on what swingweight your demo clubs are. This is the reason to have them in the first place.

The point of this is to explain that if the clubs are built to standard specifications, then it is logical that the swingweight will fall into a normal range. But if you are a true clubfitter, and you are fitting and building clubs to lengths other than "standard," then expect the swingweights to deviate. When assembling the club, then you can concentrate on the swingweight by matching all the woods and numbered irons to be the same within the set, provided the shafts are similar.
