I get about 200-300ft of climb out of my Commander with one unfeathered. If the gear is out, it's down to about zero, maybe the slightest climb in ideal conditions. This is at SL.
So if something happens at rotation, gear still out and you can't feather, then it's a little problematic. Close the other and land straight ahead.
