The main concern is the overall capacity of the packs under normal use and as long as it is within a reasonable tolerance (say, 20% of each other), and you keep and eye on your cell voltages, series packs should be no issue...
What you are failing to understand is that the pack with higher resistance won't let the battery drain equal capacity along with the pack with lower resistance, you end up killing the better performing pack with lower resistance as that pack will dump it's capacity quicker... you won't get the full capacity of both packs combined when each pack has different IR, but yes in a 5 min qual it's probably no big deal, but trying to get mix matched packs to last a 10 min main was nothing short of a disaster in my experience.
Everything stated by SMC is 100% legit, please re-read the article I linked, they know what they are talking about.
I will never run separate packs in series ever again
