I prefer single triggers for hunting. Getting the desired trigger pull is simple if you understand the geometry, measure correctly, and do an accurate inlet. Either type needs the same accuracy in position to get the desired trigger pull (unset in the DST case). I would pick what you want for the rifle and go with it. It would be worthwhile taking a block of wood and inleting it for the lock and trigger to verify the layout and see what issues arise before working on the stock.
