Is the Aviator Flight Line worth it?

[jeanna]

I was hoping it could allow my B&G to fly high and at full speed outside. After watching the video, I see that she'd be limited to flying pretty low. My house is pretty spacious with high ceilings so she gets a considerable amount of flight time daily, but it would be so wonderful for her to fly outside. But is it worth paying $50 for a flight line that will allow her to fly pretty much the same as she does inside the house?
