Finally! They all seem to come up with the missing details eventually.
As long as you're not also announcing the game over the PA system, you
don't have to worry about feedback, but you probably don't want to use
an omni either unless you have an enclosed booth, since it's probably
pretty noisy on the court. A headset mic is usually best for that kind
of application, and that's why your station uses them.

I only wanted the vintage fatboy because I love the way it looks.

I can understand the inspiration. Dave Letterman doesn't really need a
vintage RCA mic, but it just looks right to him. I understand that he
occasionally taps it with a pencil and it sounds live, but I wouldn't
be surprised if his primary audio actually comes from a condenser clip-
on mic that the engineers are more comfortable with.

So why don't you use a headset or clip-on mic connected to the
telephone interface, set up the 55, and pretend that's what you're
broadcasting through?
