Could anyone comment on the difference between the two in regards to free ride kiting. Boosting would be an advantage. I weigh 83kgs. I already have a quiver of Edges 7,9,11,13,15.
I swopped the 2013 17 edge for 17 zephyr .The zephyr is more all round free ride and for me more enjoyable. Goes upwind easily. Turns faster and has a tighter turning arc than edge. Similar bar pressure and feel as the edge. At 95 kgs I feel the edge developed more low down power and powered up earlier, I was using my axis patrol l/wind tt 144/46 and am kiting from 10 knots. Zephyr easy to boost and plenty hang time, the more powered up you can hold it the higher you go, have carried it from 10 to 23 knots, really good for boosting 14/ 23 knots ,I like to be well powered up. I have the 19 edge for 8/15 knots on same tt and feel 19 edge better than 17 way more low down power and have carried it to 18 knots. you can youse it in similar style as zephyr video and on a sector board. Zephyr has a great wing range and easy to control at its upper wind range, because of this I feel you may find your 15 edge and 17 zephyr too close together, try a demo. At 22 knots I change down to 11 edge or 10 catalyst. The new zephyr is a really nice kite I would recommend.
