We are using heavier wire at Long Beach Island, and while we've neither
made any comparisons nor any measurements, our experiences indicate
that for BOG's on the sand at least, anything in excess of 1000'
resulted in diminishing returns. We've largely settled on about 800'
after using lengths from 500 to 1500' in the past.
