For commercial tower installation watch those wind load numbers, most towers want a 90-100+ wind load, 120+ within 5 miles of navigable water. As far as efficiency goes there is no such thing as a multi-band antenna, the ham patterns are generally so high on the horizon that you would need a good aeronautical audience to make it useful. The ham antennas usually get damaged fast unless you add braces about 2/3 to the top for support in wind, if you could mount them upside down without filling with water along with the brace they would work good - or used at home stations as intended.
