I've used all of the above.  The fastest for us is OA dribble, at less than
30 sec for a double, with better efficacy than a single vaporization.

As far as safety, me and all my crew, after years of experience with all
the aforementioned methods,  feel that OAV is the most hazardous to the
operator.

I strongly question the penetration of OAV into the cluster with such a
quick application.  I hope to provide hard data on this next season.
Medhat has already investigated this deeply.
