Plenty of response from 500 drivers but no response from deer capture pilots.
"C" OK 6000' and below.
"D" or ("E" is the same) bit better than "C" although be careful with heavier weight and harder to muscle around.
NOTAR - Don't bother.
530 F or FF - no range/endurance. Probably a bit lethargic on governor response for deer capture. I would caution against governor issues and stall on a 530. Has bitten a few people.
"C" or "D/E" is your best option. "C" is possibly the second choice.
