Sorry, I'm not going to stick my neck above the parapet and suggest alternative ways to conduct your departures. If you have to operate in marginal conditions, your best bet is to get in a simulator and simulate your particular conditions and find out what sort of crash feels best. For example, you may find that clearing the fence around your helipad and crashing into the clear ground beyond gives you a reduced impact if the engine failure happens above a particular height, whereas you are better falling vertically than crashing into the fence if the engine failure occurs below that height.
