Some great advice Steve. I find getting the depth right very important. Generally they bite near the bottom (as this is where the weed and burley tend to be) so I always let out my float stopper to find how deep it is (you hit the bottom when your float become horizontal). I then start by fishing a metre and a half above it. Sometimes the floor is uneven, and your float will get snagged along the drift, so keep changing the depth of the float until your drift does not get snagged. BTW - you need to have a running float, ie a stopper knot on the line to engage the float, if you do not use a running float (ie fixed float) it makes it very difficult to cast - also the strike is not very good, as you strike the float first in this instance - Arrgghhhh, there are so many little things to luderick fishing, it does take a while to get used to, but is worth it. This used to be the only type of fishing I did, until I start chasing pelagics.
Best you read a book about it, or even better take Steve up on his offer to show you the ropes, it will save you months of trial and error. Hell, I have not fished blackfish for so long I may need to get some lessons from Stve
Hey Steve, I am a mad Roosters supporter too, thank god they finally won their 1000th game on Wednesday. We will get through this rough patch, a lot of good youngsters coming up, we will be up there again very soon.
