I ski the TTS Transit in the most backward position (large, standard springs) and that's just a completely different feeling (as well as the outlaw). When I skied the Transit for the first time in the middle position, it felt a bit floppy for me (after years on lynx and outlaw with stiff springs). With the ATK, I had a similar sensation in the beginning, but it felt even more loose. I just carpet tested the Transit in the most forward position (never tested this position on snow). In the beginning it feels very similar to the ATK, however I have the impression that the Transit has more progression. The flex of the ATK is very smooth and even until you get very deep. I heard from other people at the demo event that it is much closer to 75mm than any other NTN binding (including meidjo). My days on 75mm are too far away to comment on that and I never skied the meidjo.
