I have said this before, but I am a softbooter who rides hardboots sometimes.
Softboot angles 23/7, or so.
Hardboot angles 53/50, or so.
For those thinking of a wider softboot board. I have sz 12 feet and ride a 27 wide freeride board. As the boards get wider, they get to be harder to ride in crud, they get on top of it (sometimes that's ok), instead of blasting through.
Thanks for the flashbacks, sometimes I forget how far we have come. By contrast, I rode Sims bindings then Burton freestyles with the really soft Burton freestyle boots. I HATED the Elfgen/Gnu bindings.
