I can't see myself planning my 100k milestone benefit until I've selected my 90k.
And realistically, I can't see myself selecting my 20k until December.
I can take a pretty good guess what I'd like right now, but barring expiration dates (i.e. if I pick MLL passes on December 15 does that mean they're only valid for 2 weeks, etc.), there seems to be minimal reason to pick things early.
I don't want to give up a PR to take an SQC bonus... unless the SQC bonuses are the difference between requalifying or not. And I won't know that for sure until December.
