Hi Mick and welcome to the site. You asked a tough question to get good reliable info on. Many who hunt that area are tight lipped about it's secrets and probably would rather you put in for another zone altogether as there is plenty of competition for the tags awarded as is.
I would think one of the first things you need to do is figure if you are willing to wait, maybe for years and years, until you do get drawn. Getting drawn might be a good starting point. Once you have tags in hand, you might find out what you are looking for here by going back thru the archives, back pages, finding some posts about 102 and PM'ing some of those guys that offered general info out in the open forum. Many will help you thru a PM where they will keep quiet out here in the open to everyone forum. Good Luck!
Joey
