I think the "sweet spot" for hammocks is whatever temperature causes you to toss off the blankets at home. I'm happy setting the thermostat near 60 or the upper 50s (my wife won't let it go any lower, even if I was inclined), but I take full advantage of the blankets and the insulating properties of the bed. Keep in mind that with no under insulation, your backside will be close to the external temperature. 50 degrees, fully clothed and moving around is fine, but lying still with all my clothing compressed to almost nothing is not warm.
I would say that mid to upper 60s I'm happy with my bag liner and lying on top of my synthetic sleeping bag. Lower than that and I'm in my bag. And once I'm in my bag, I'm probably wishing for a little more insulation underneath.
So just keep in mind that without insulation, your backside is basically outside.
