Bryson DeChambeau's single length irons are all matched. The BioMatch method of matching golf clubs determines the optimum mass of each club in the set. The optimum mass is a function of club length, club moment of inertia, and lie angle as well as the properties of the golfer. As all these variables are identical for all of Bryson DeChambeau's irons, the BioMatch method will yield the same optimum weight for all his irons. As all his irons do have the same weight, they are matched according to the BioMatch method.
Unfortunately only his irons are matched. The rest of his clubs can easily be matched by the BioMatch method so that he can use the same swing for all his clubs, without altering the length of the clubs or the weight of the club heads. The optimum weight of each club is obtained by inserting the appropriate size of weight into the grip end of the club.
