Missed varroa treatment. What would you do?

I had a call from a beekeeper this morning who missed treating his two colonies. Options could be

a) leave until Oxalic Acid time in December/January
b) use Bayvarol/Apistan (resistance may be an issue).
c) use Apivar or an amitraz based insecticide
d) use something else
e) do nothing and hope they're OK 'till spring

Perhaps first thing is to assess severity by seeing how many varroa are dropping. Or find someone with an OA vaporiser to do an oxalic acid "accelerated drop" on them.

I'm not sure how realistic a drop count would be at this time of year - but might indicate a horror story or not. I guess icing sugar dusting (remember that?) might give some indication of the severity of an infestation although it's not the time of year for that. Without a vaporiser, maybe some Amitraz based treatment as something that won't disturb the colony too much.
