240 isn't all that heavy....
Honestly, I would say go with the Union Force if you want something that will surely hold up.
With that weight, a canted footbed is also something you may pay attention to.
I'm not a small guy and my next bindings will probably be Rome Targa or Ride Alpha MVMNT. Currently run Ride NRc and absolutely love them. They're started to show a lot of wear though... I've got almost 50 days on them
