i agree with the above, 3-4lb leaders are just not needed. personally i would go with 6lb or 8lb if the water is a little dirtier, first if you go with a high quality leader like seagaur the diameter will be far smaller than that of say cheap fluorocarbon like trilene or berkley. personally i find smaller roe bags, smaller hooks and having your last shot atleast a foot above your roe bag to be all the stealth you need.
