I've seen that before, but since the Vivitar 285HV's head is so large, I didn't think that Lumiquest holder would fit it. It might work just fine for the 580EX, though. Personally, I don't like sticking velcro to my flash, but thousands do it. It's easy and convenient, however, once all your gels have velcro on them they get rather bulky to organize and store.
