Ok Sir!
In summary then - when flying over rugged terrain such as Hawaii try and get as much height as you can and fly over areas where there are potential landing spots in case of an engine failure and when spraying, if the engine cuts, initially keep some collective applied, climb to gain height and then perform a cushioned landing as you would if you were doing an auto from within the HV cure such as might be necessary if you had an engine failure while using a long sling line?
