Yes, cost effective. I would have had to use two P100s plus a ferrule on the leading edge, so I chose to use the .180. The weight difference wasn't much if any. In the wind speed that I want to fly a UL, I don't think the flexibility between the two makes much difference. This is all my humble opinion. With my flying expertise, there will be no videos.
I was just trying to keep my kite in the air at a lower wind speed.
