Pruning Mature Podocarpus

[taropatch]

Could use advice on pruning mature podocarpus (yew). The 25 footers will be topped to maybe 10-12 feet. How do you prune the side branches so they don't grow back so quickly? These side branches extend 5-6 feet. Cut all the way back to the trunk and let it make new side shoots or cut 'em back about half way? Thought some here may have already faced this dilemma and have some experience.
