Happy Landings!
Never had the donkey quit on me yet, but I'm VERY confident I'd get it on the ground in one piece cos - like you I suspect - I was taught engine offs to the ground from day one. Yes, there was plenty of 500ft recoveries in the local area, but every other landing I ever made during training was to the ground.
Reference Shaun's grass-v-tarmac thing, above, I also got to do high speed powered run-ons on smooth concrete in a range of MD's at the factory as part of some type training, and I can tell you nothing builds confidence like actually hitting the ground again and again and again. Get some in, I say!
