Hey Tommy..  When i go to the tackle store i buy those little purple plastic containers that have 6 different sinker sections in them..  They are the best as they have a wide range of weight that can be used.  I just vary the weight depending on how strong the current is and where the fish are on the echo.  If they are on the bottom, then a bit more weight to keep it down.. If they are mid-range, then no weight and let it float past them..

With those sorts of jigs, it is best to get the lead headed hooks and instead of putting a hook on like mine, use the weighted jig heads instead.  I reckon those lures are best used up north as I haven't had much success with them down this way... But I've always tended towards bait a bit more than an lures/soft plastics.. But I'm intrigued about them all the same and want to see if i can catch something other than bream on them.
