Sorry you lost your deer but I've shot both Grim Reapers and Fixed. I do like shooting fixed better but if I choose any mechanical it will be a Grim REaper Razor Tip. I shot 4 deer with the Reapers watched all fall within sight got down found my arrow all the blades were closed EXCEPT the deer were torn to peices inside where the blades opened. I don't know if it was the design or what but I've had 100% recovery rate with a Grim Reaper. But I have lost deer with fixed and mechanical so it's a never ending battle. With a fixed you don't have to worry about blades opening.
