Dennis,
For years I did as you did and never staggered the length of my leadouts. At a contest in Seattle in the early 80's I noticed that Paul Walker had a rather excessive stagger on his. I ask and he said they will never catch done like that. A week or so later while flying with cable leadouts, mine hooked. Luckily they came loose without a crash. Took the plane home and staggered the cables. Have done so ever since. My standard stagger for the past 5 or 6 years is 5.25" with the controls neutral.
