I seem to fish a bit lighter than most , I fish 30lb braid and 4-6oz leads on the ground and try a 7oz on the wrecks before going up to 8 or 10 if I find I have to , I don't fish multiple hook rigs though which helps keep the weight needed down to a minimum , my favourite pirks are 200grms but I have the same pattern in 300 grams for when the drift picks up (or at least I did before the wrecks ate them all last time out

)
I find a 7oz torpedo lead works a 4" shad perfectly most of the time , which suits me fine , I hate dragging excess lead up to the boat all the time and enjoy the fight of the fish more with less lead for it to drag around.
If I do want to fish bait , I still try and keep the weight down to a minimum by fishig a one hook rig over the wrecks , but can get away with a standard 3 hook daylight or hokkai rig on the ground.
I see people advocating light rods and line , yet big leads still seem to be the norm , I can't fish a pound of lead on a 12lb rod

, it just dosn't feel right.
I fish mostly alone , so no other lines to tangle with , but I like my line straight up and down (most of the time

) so tangles with others still shouldn't be a problem .
