Speaking of Kinetic recovery ropes generally as we know it stretches to 30% of its length before the actual pull happens. And this is additional room requirement.
Shortening or doubling the length of the kinetic rope I believe has nothing to do with the amount of force generated and transmitted to the rope to stretch , recover and recoil more than the situation ( tight space to operate the tug , terrain ( soft /super soft sand , wider space with incline not in favour of both the recovering car and car being recovered , intention to redirect for better self recovery ) ... each situation has its own dilemma which needs a moment of look and thinking of what is best for any particular given situation.
The more you see the more you become familiar and bit more experienced .. and this is another reason why I do keep bouncing on rubber on weekly basis ( that’s me ) 😅
