Re: Capstan winches for recovery
Not a perfect match to your question, but we (Fire Dept) use a receiver mounted capstan on our Heavy Rescue truck to aid in low slope rescues/recoveries. Same as above, low stretch poly braid rope is preferred. Anything beyond 300' of rope makes a mess at your feet. For game I'd suggest multiple pulls of lesser length if you can relocate with ease.
Great piece of kit, would make a great game recovery system.
