Hi drfox, and welcome to the forum as well as fly fishing!
Take a look at the link below, you will find reviews by a number of different fishers, most of which mention flies & methods. I have never fished here myself, but it seems like buzzers were a very good choice on your first trip.
It looks like a fishery where floating line will suit most of the time. In terms of methods, its often a case of just making sure your fly is in the water.
