Don't Rush Anything....
You have selected a great guide and area. One thing that you won't find as much is that you should take your time and make sure you get the sheep that you want.
There is a video Black Shale, White Sheep by Ric French and you will find that many clients and sheep hunters in general will rush things.
You might have to hump it to get in position but soon as you get there slow everything down and do things instinctively.
You might also make sure that you dont compete with the guide or try to be super man. Instead be quiet, joking and have fun. The guide will work so much harder for you.
When your feet are thrashed elevate them and take a blood thinner.NSAID.
Have fun and tell us how it went.
Also take the very best point and shoot digital camera you can.
