Swing flags
One of my guard friends using her swing flags as wings x] We're using them for our middler, and my rough guess is there's somewhere between 4 and 6 inches of pole out the bottom of the silk for a handle. One of the lieutenants also uses a set of metallic-ish swing flags with square silks to highlight a soloist in the closer.
Weapons line includes both rifles and sabres this year, and we've got regular flags for the opener and closer... Though the silks on the opener flags turned out to be smaller than they expected, so they've got them on 5 1/2 foot poles as opposed to the regular 6 footers.
There's also a dance feature in the closer during the solo. It was hard to tell from the press box what the dancers were supposed to be doing, so now they've got these big blue and silver orb things with a stick out the bottom for a handle and 5 points around it to make it look like a star to make their movements more obvious. We've fondly dubbed them "the huge-a** Christmas ornaments." :]
Also, I would just like to tell you all that if your director ever starts talking about using particularly huge props, TALK THEM THE HECK OUT OF IT. Marcus' stuff was a right pain to maneuver at our invitational last year. Those stupid grapes didn't fit in the tunnel leading to the field, so they brought them up over the chain link fence, down the little hill on the other side, and pushed them on-field from there... It was absolutely terrible to deal with.
