I got fitted for a set of mp18 sc in the summer and ordered through the account where I work (asst. pro)but busted my shoulder and haven't used them since buying them- they are brand new in the wrappers. I'm just starting up properly again and demoed the 919 tour and much prefer the look and feel I got. Would Mizuno swap these or is it a case of selling the 18s and reordering.. anyone know?
