Hi. there is no way to answer your question without further information. You would need to provide specific photometric data for the second and third choices, and also provide specific information for how big your stage is, how far away is the audience from the scrim, how far away the light source will be from the scrim, and what wattage lamps you intend to use in the fixtures.

My initial inclination is that only two Selecon Cycs or Huis is nowhere near sufficient to provide even illumination across the surface of a 30 foot wide scrim. The LED sources are likely going to put out a whole lot less light than an incandescent source would. If these are your only choices, then I would think the incandescent sources would be the best ones, but you might need a lot more than just two fixtures for each color.
