I work in a 100+ year old Chataqua barn and we produce 5 musicals a year Facility seats 500+ We have never had fly space and have used a variety of systems over the years to deploy drops... Roller track, drum roller manual operation (home made one off) Roman shade style etc. All are unsatisfactory in their own way.. Our proscenium height is only 14 feet and really only a few feet working room above that. I ran across the dmx roller drop on the rose brand site.. It looks like it could be Manna from heaven. Anyone here with real world experience with one of these? Hangs from just 2 rigging points, so looks pretty versatile.
