Thank you all for the advice. I'd like to get new bindings to avoid material fatigue and hopefully have them last for a long time. Luckily my CATEKs failed while stopped, but this could have been real bad while riding.
The part I am not sure about is the stiffness. Reading about the TD3 Sidewinders on Bomber they say that "people used to think that stiffer is better". I thought the same, but after reading the comments this may not be the case any more.
I am interested in the convenience of step-ins, but not tied to it if it's not a good choice for the riding experience. So I need to figure out of I like the "additional stiffness" that comes with step-ins or if I want to mitigate that with the options the TD3 Sidewinders have to offer.
So, from your experience does less stiffness not take away the control?
