On the banning of leaders and lead clips, again nothing wrong with the products just the inexperienced users of said items. You don't ban cars because of a few terrible drivers, this is the same IMO.
My lead always comes off on the take when I want it too, 4-5oz flat pear lead, korda hybrid clips, tail rubber on lightly, its off on the take, which I want on a weedy/snaggy lake. If I want to keep the lead I go for a heli set-up.
Even a running setup will tangle and hold onto the lead if there's 20+ yards of coiled line attached still. Pike are a pain for doing this - biting you off at the rod tips, happens on point swims regular.
