I don't know if this can be found everywhere but I was perusing the meat case at Costco and came across prime packers for $2.69 a pound! If I can find more will full packers freeze well?
The "full" briskets I've seen at Costco in my area in cryovac are not what I'd call a full packer. They trim most of the point off at the plant and only a remnant of a point is left on the flat in the cryovac. Definitely not what I'd call a "full packer".
To answer your question, yes, brisket freezes well. In fact, there are teams that'll cook nothing other than a defrosted brisket in competition.
