Am I missing something, or are folks just making this way too complicated?
When we wanted a shorter or longer rope, we literally tied an overhand knot at the length we wanted and looped the rope over the tow point. Problem solved. When we wanted a longer rope, we used the two loops (which all tow ropes have on each end from the factory) and they were connected. no knots, no nothing. And again, used and overhand knot/loop to put over the tow point. And that loop can be put in the middle of a section of rope at 5ft, 10ft, 20ft or whatever you need on that particular day.
This must come from our days of water skiing, when you took off lengths when running a slalom course. But those ropes you literally unlooped a section to take 10' off. Our wake ropes come the same way. Use that same theory here.
We never went out in search of 5 or 10ft of tow rope. Or bought generic rope and cut it to length. When you leave tow ropes whole, they become whatever you need them to be for the task at hand. With very simple knots that come out in seconds, but hold all day when needed.
And when it comes to storing the excess rope, you use a velcro cord minder and lash it to the tower till done. Or when in storage, no tangles or mess. Work smarter, not harder guys. This is far from rocket science.
I would say our tube ropes are hanging from the center of the tower more than stowed on a tubing day, as it's a great place to drip dry, and will never get tangled when managed.
