I have tried the sled and they do make it a bit easier but still tough to justify the cost as it does not make it that much easier. 150# gutted deer, you must have monster deer. I live in NY and even a 3.5 year old buck will go about 150 dressed most of the time. I have killed an awful lot of deer and my biggest was a doe at 187 dressed. The wheeled carts work well depending on the location of the kill, field edge and along corn fields, but down in the woods are useless where I hunt. Let us know what ya think! Shawn
