what is the best way to increase the reach of a flah? i have profotos. i need to shoot a couple on a bridge, but cannot get closer than about 7m to them, and i only have 1200ws in may pack. would a profresnel do the job? or a 7' giant reflector? it is daylight and outdoors.

OK, I don't understand! :confused: Are you talking about increasing the reach of a flash?
Most flashes will certainly cover 7m easily, so I don't understand your question.
