I had problems with just one 8' high wire. Trees bowed too much under fruit load. Trees midway between trellis posts pulled the wire down causing the entire row to be pulled down and bowed. Bamboo was ¾" diameter. One wire added later at 5" alleviated the problem.

Obviously there are limits, but in our own case, for our single line orchards we have opted for 4 ft. x 11ft., and we have found this a good spacing for the more vigorous Elstar variety (more vigorous than Golden Delicious or Jonagold at least). We do not grow the trees as high as at lower latitudes (more mutual shading from taller trees when you come this far North), and have found that a limit of about 5 ½ to 6 feet height of cropping wall works well. In practice, this wall commences about 2 feet above the ground, and finishes at 7.5 feet, facilitating all harvesting and pruning from ground level.
