Good Morning, I’m glassing quad fins for the first time using the McKee Formula. My goal is to ride this shortboard in steep waist/head high waves, so pivot and hold are more important than drive. I followed the math and measurements and still have four days before I glass these on, so I thought it’d be wise to run this by the experts here. Also see, pic below:
