Due to Byregot's Blessing being way overpowered, it's more like find the cheapest way to get 6-8 IQ stacks and then Byregot's Blessing will take care of the rest. Since on average, SH2 + 5 hasty touch = SH2 + 4 basic touch, but the former uses 72 less CP and you most certainly can get 10 durability back for 72 CP, so SH2 + Hasty is guaranteed to win out in the long run barring extremely bad luck. Of course since Byregot only need at most 8 stacks of IQ to finish the job, if you got enough CP you might as well use the Basic Touch which removes any uncertainty.
