REPLY: 
That's correct, but remember... A parallel resonant circuit has
circulating current inside it. As you drop the inductance of the choke
the circulating current increases and if you drop it too far you run
the risk of burning up the choke, especially when it's wound with
small diameter wire. Everything is a compromise. No free lunch. 

Just something to keep in mind.
