The biggest thing right now is that I am 155 lbs, down 10 lbs from what I thought I was flying at. 70kgs now compared to 75kgs and my first wing is rated for 85-105kgs while the new one is rated for 75-95kgs. It puts me far more in the middle area of the range instead of having to ballast just to be in range. The wing flies far different with more loading on it, too light and it acts like a leaf overhead.
