Reel advice for submitting to potential managers or agencies?

Hi y'all,

From what I have searched on the sub, I couldn't find anything addressing this specific question, although some threads seem to debate using audition clips in reels etc.

My problem(s):

I have booked lots of paid work (student films, but also a feature, TV, and indie shorts) in what I would say is a short time (just started out this May), but am looking to up my game with representation. I notice in most calls on their sites they want demo reels, but it would likely be several months before I received copies of my work to put one together.

So,

Should I A) edit together my sharpest self-tapes and submit asap, or B) just wait till I have enough external projects to put together to send out for potential representation?

If nec., I am a 32yo M in the mid-Atlantic region.

THANKS!
