How come two chokes are smaller than 1? It seems unlikely.

the 2 chokes might be physically smaller due to lower current and
therefore thinner wire. It probably has something to do with the inside
diameter and wire thickness of the physically larger choke. I might
also guess that the larger choke is rated WAY more than twice the
current of the smaller ones. Or, it could have a potting can around it
making the whole thing 'that much bigger'.

Maybe it would work better to get the right choke for the job?

/me is a fan of LC or LCLC to take full advantage of the input
inductor's behavior of inducing voltage to maintain current flow.
