Sunfish take a holiday in QLD (gold coast area) and go see J. Chesterfield V.Salmon or in Bne A. Dunbar. These are the sorts of people that you are looking for. They've been there done that and each time you fly with them you learn so much. J. Eglen (RIP) was another one of these priceless people in the SE QLD area. Didn't know him from a bar of soap went flying with him and used the skills imparted for years to come - to top it off it was extreemly affordable.
