One of the issues regarding the addition of dayglo stripes - as with the Vigilant - according to the psychologist at IFS, was that the addition of the stripes effectively makes the wings look smaller; it is only easier to see once you actually have a tally (he explained it better than i ever could
). It doesn't actually help you see the contact in the first place. You could, of course, argue that that is less relevant when you are only doing 120 kts (ish).
