“No one ever said they will pasken like Bais Shammai in every instance.”
Oh. I thought that was what we were arguing about. I was saying that pshat is that in the future they will be able to pasken like Bais Shammai. You were saying pshat was that they will have to pasken like Bais Shammai.
If all you meant was they are more likely to pasken like Bais Shammai on any given question then we agree.
What I meant by “bechira” was how a given member of the Sanhedrin understands.
