I always remember, altitude = time. If your engine fails straight after take-off, you can't afford to be too picky.
With that said, its hard to make judgements about the landing field without an engine to help you inspect it (its a forced landing, not a precautionary landing). Your goal in a forced landing is to survive - landing without injury and a damaged aircraft is a bonus.
I've heard heaps of stories about successful forced landings, if you can't learn through your own experience, learn through someone else's.
