Tweed bait will catch you fish if they are around.I've lost count of the number of Flathead,bream,whiting,flounder,tailor etc i've caught on it over the decades and I'm no expert fisherman..
Remember if your fishing with the best gear and bait and the fish aren't around or hungry,you will still come home empty handed.
Some real good captures have been caught on stinky old prawns etc and using servo bait is no different.
Use the freshest bait you can get first,but don't be discouraged by using servo bait if necessary.
