I have been given a plant (Ficus rubiginosa) for a present which needs drastic pruning back to the trunk. I have read Leong Kwong's book Ficus in the Temperate Climate in which he gives advice on pruning back an established plant to a bare(-ish) trunk. I have heard of two different methods of doing this kind of pruning -
a) Cut back branch leaving a stub in order to reduce the bleeding of sap from the wound and chop the stub off at a later date.
b) Cut back all the way to the trunk and tidy up the wound with the concave (?) branch cutters in order to help the plant heal quickly
Which method would be better on a developed fig?
I know they tend to bleed profusely and I would like to limit this but wouldn't using option (a) mean that the tree has to repair itself twice for the same effect??
Here's a couple of photos of the plant in question - Any help greatly appreciated


Cheers
Edit: Forgot to add the trunk is around 90mm at the base.
