BBM that is correct. Most lures will suffer with terminal tackle. This doesnt include split rings that come standard on certain lures.
I use 5 feet leader as to leave enough room between the lure and teaser. At the end of the leader I use a barrel swivel. Some guys with worse OCD then I have wont even use the swivel!
Im am a bait man by default but the times I do use artificials I get maximum results.
