Trackers never hurt and there's almost no reason not to use them, but there's no substitute for pre-production and field testing. The only failure is failure to plan. Ideally your markers would be high contrast, however you can place darker green markers on a green screen which can be entirely keyed out if the artist doesn't need them, but will still be ...
