I'm literally throwing my Calumet Elite lighting systems in the dumpster where they belong. I need a light weight system for quick location shoots. Anybody have anything good or bad to say about the Dyna-Lite packs and 2040 heads? The problem with the Elites are the short flash tube life and the obsene replacement cost, plus the cables short out and I believe one of those shorts took out a pack. I've got Speedotron Black Line packs and heads that are three to four times as old as the Elites and give me much better service, I just don't want to carry their weight on some smaller shoots.
