mate that is way to heavey a leader in my opinion...
i rig mine with 80lb fluro leader connected to a swivel-split ring-then a snapp and connect that to the lure it gives aroud 2 inches of distance from the lure and it works a treat and I seem to get alot more bites when they are shy.you might loose a lure or 2 but then you get to buy more.
the leader does not need to be huge as it will affect the way the lure swims same as aything you attatch but i find this normally gives me enough protection just keep diving a little after the first hookup.... i was driving through schools of them last week with this setup 4 lures out the back and lost 1 lure and landed 6 fish... 1 lure for 6 8kg fish is ok for me
