I don't. It's a good choice. The shape lets them stand and also lets you control light. Used the other direction gives good wrap. They make good scrims against hard sun, too.
The ones on the floor were to create brightness on the metal reflection off the belt. Not so much for this particular shot, but for the majority of shots with the belt worn around the waist, lighting it was a bit of a chore. There was a lot of dark surfaces present that left the belt mostly black and unable to recognize the "Havoc" emblem in gold across the front. I normally carry a 5' skrim, but forgot it on this occasion - the extra brollies fit the purpose and worked well. Thanks all for the kind words on the end result.
