Here's my take on them. The SL baseplate, which the charger has is much stiffer than the Force baseplate. I'm going to assume the carbon highback is going to be stiffer than the Forces both torsionally and laterally, only because its a full back and it's carbon. The asym ankle straps are a bit softer than those that come on the Force so it increase comfort but does compromise a little bit of toe side response, but it's hardly noticable, and ultimately comes down to preference. Some people complain that the Force strap is too hard.
Now, I'm not too familiar with the Cygnus but from my understanding it's an all mtn board with a freestyle shape. The board/binding flex combo again comes down to personal preference.
