I think I saw these add 9-10 g of weight to the head end of the club, which would increase swingweight by 5. Wouldn’t this affect fitting?
I think it is a little less than 5 swingweights. It can vary slightly depending on the shaft weight. Those that have used it have told us it does not affect the fitting. Players with refined senses of feel might notice the slightly heavier weight, but the benefits of being able to test multiple shafts quickly in a single head, or multiple heads on a single shaft, far outweigh any weight variance from the club conex.
