A couple of weeks ago while hanging out with West Coast Camps instructor Conor Bayak (who's a blast to hang out with by the way), we got on the subject on line length. We were pulling riders all day long, with a wide range of ability, so we were constantly adjusting the weight / line length / speed formula.
He brought to my attention that some of the top riders are riding shorter lines. Last I heard, I think Harley rides at 72' or something. It sounds like a lot of the camp instructors also ride between 70-75 feet.
So after 5 years of riding 80 feet, I dropped down to 75, dropped about 700 pounds of ballast (all from the rear), and shaved 1 mph off of my speed. A couple of my buddies rode 70' yesterday, and were going huge.
After one set I wondered why I ever went to 80. Everything was timed better. I was popping bigger than ever, the crashes were far less intense, and I found myself working to get old tricks back. The wake was bigger than ever, we got on plane much faster, and saved 10 gallons of fuel for the day.
Has anyone else started shortening the line from 80 feet?
