Getting a "portable" /19 or /20

With the demise of Winstar/good.net locally,
and us having to renumber anyway, I am getting
started on the idea of getting a 'portable'
/19 from Arin. We are currently using a non-portable /20
and a couple of /24's.

Any words of advice as we start this process?
I'd like to do this right the first time
and could use an experienced viewpoint.
