Hello,
new aerodynamics rig works well. i got one and feel the difference. it's hard to say how much but i got this from www.adrenalinbase.com website, looks like VKB team use this equipment.
"Wind tunnel testing
Wind tunnel testing of the Adrenalin HYBRID rig compared to a “classic” rig design, as the ZAK, performed by VKB, summer 2006.
With the help of Hans Holmefjord, Oyvind Lokeberg performed as the test dummy, wearing two different suits (track suit & wingsuit). He got lots of data (lift, drag, glide ratio,…)
The setup with HYBRID rig showed lower drag in all tests of approximately 10-15 % compared to using the classic design. The reduced drag forces contributed to an overall better glide ratio, between 5 and 20%"
