As a vet, I can definitely recommend neutering, like others say, stops fights, unwanted litters, and the chances of him straying to find a lady friend, which is the most common reason for car accidents.
Personally, I would neuter once he reaches a certain size rather than age, and as long as he's reasonably well developed, and has large enough testicles to get hold of, then he's ready to do, as you say, let the vet have a check when you are in next on Thursday.
There is discussion in the vet fraternity that early neutering before puberty can mean less risky surgery as the blood vessels etc have grown less, and so the risks of bleeding are reduced. However, smaller animals can lose heat quickly, so we tuck them up well with hot water bottles and warm blankets while they are being operated on and recovering. Young animals are particularly tough and resilient, so normally are up and bouncing around very quickly!
Hopefully he'll get done soon and then it'll all be over, and he can become the fantastic hunter that you require!
