Just had a fun day with my brother Svein and I(Jarl) up on the hill doing some testing. Pretty interesting to be bouncing around from one binding to the next and all on the same skis(good thing about having insert-skis). The layout was: K2 Work Stinx size 181 and started the day with Rottefella NTN, then went to the NT Bulldog binding with the Voile SX binding being last. Really good info from that day and here is a little video to show you how everything worked in real-time.
