Unassisted go farthest from boat weighted go closer longest leads farthest away in each category. So an example running 4 boards on one side the farthest would be 120 unassisted then 80 unassisted then 50/120 2oz then closest would be 50/80 3 oz that’s how I run them and have very few tangles you do need to leave a slightly larger space between unassisted and weighted boards because the weighted boards will run back a little more than the unassisted.
