@julesh Yeah, this is not easy... With the major funding models, I really have to ask myself whether it is worth getting the money at all.
If I spend all the time that is needed to get enough money to hire one (or god forbid, two) postdocs for a couple years, what I get in return is a lot of management overhead and realistically speaking not a ton of "added power" in my research (because the mission of a postdoc is rightly Get A Job After This, not Make a Long Term Impact). I don't think this problem can be solved in a model where only the tiniest minority of researchers (faculty like us) have any long-term job stability.
Perhaps it is different in more applied areas or lab sciences, but I have for this reason felt that the reason to hire postdocs is mainly to support the continued health of the field by giving good young people a job and a chance to catch their breath before going on the faculty market. If I wanted my own research to go as rapidly as possible, I would hire nobody...
