It would be a good idea to actually run some numbers and tests on that, depending on growth.

It would be very interesting to know how many blood hunters can be sustained by a growth 3 province without having the population shrink.

Then you would choose your strategy depending on whether you want to have 5000-person income permanently + moderate blood slave income (blood hunting countered by growth, gold income blocked by the price of patrollers), a growing number of persons but only part of the income (that should pay in the end, but how long with the tax control method ?).

I think I answered my own question already though. I doubt that patrollers costs less that the tax control method "costs" your gold income, and "tax control" does not seem (according to the manual unrest mechanism) to reduce the population, while patrolling does...
