Go for it!
John used to be known as 'Mr Sika' and did a lot of business with the likes of Diana - the recently insolvent top class hunting outfitter.
If he was still tied in with them, there is a fair chance he will have some spare slots - otherwise, he needs to be booked well in advance.
I went over on a cull package, though trophy stags were available as well as a few wild goats. The grounds are excellent, and if you are proved reliable, he is not above giving you a map of a block and suggesting you hunt it yourself. Conversely, he has some excellent guys working with him as stalkers to ensure you get into the beasts asp.
Open hill stalking, thick pine forest interspersed with rides, boggy valley bottoms - whatever 'your' stalking preference, its there!
One thing that is not in doubt is the sheer volume of deer running around - I have never seen such a concentration of animals. Expect to be taking 2-3 per day.
Great place to go as a party - the pub is stalker friendly, and well used to small mobs of blokes dressed like trees, each with a severe Guinness dehydration problem!
