Grant Horvat is a popular YouTube golfer who made a name for himself with the Good Good crew before he struck out on his own channel. His channel has since featured PGA Tour players like Jon Rahm, Jason Day, and Tommy Fleetwood, as well as fellow content creators like the Bryan Bros and Micah Morris.
I thought Grant used the Qi35 for driver, woods and hybrids.
His irons are 4-8 in CB and 9-PW in MB
