Truck towed up to 740 feet and hooked up right away with a 60 fpm
thermal. In the end, topped out at 3800 feet and maxed out up to ~800 fpm.

Flew up north and found a great lift lines, barely losing any height. In my
opinion, it was a BlueSky Hang Gliding day that most pilot with little bit
off skills and luck could stay up for hours. And the Tenex 4 is nice. Most off
all, my glide ratio has improved a lot with this new harness and more (My
previously harness was a CG-1000).
