I think a stiff boot would work just fine with the universal binding; if you’re wanting to make a few downhill turns- I think the stiffer boot would help
I don’t see any downside of a stiff boot (if it’s comfortable obviously) in the universal binding- I’ve worn a pretty stiff La Sportiva boot with them, but usually a lighter weight Keen, in frigid conditions a Schnee pack boot- they all work fine
