If the wing has a reflex flap position, should they be left in take off position? Above the critical altitude with wheels up (if possible) and flaps retracted - (What is the critical altitude given the takeoff environment?) Pitch for best glide. Turn back?

Hilly treed countryside, narrow short runway in a slit in the trees with wires at one end (displaced threshold). If so, I need to be at a higher altitude before turning back. How about an airport with crossing runways? A lower critical altitude might work since less turning is required. One climb angle might result in only 1500 ft/min while a steeper angle yield 2500 ft/min - an engine out exposure difference of maybe 40 seconds for one or 25 seconds for the other. Well, I have decided to steepen my climb out somewhat for the first 1000 feet anyway - I'll try to keep it at the best L/D indication on the AOA. Ahhhh, another interruption........
