I used to like long leaders about 30ft after the swivel. Leadering a fish is fun but also dangerous I suppose...
I recently switched to wind-ons for saftey reason and other personal reasons. I don't think I'll ever live to see a wind-on fail. I buy them from Basil
www.bhptackle.com They are as good as it gets.
I use a long line clip or rubber band to attach my
light or glow stick about 20 feet back from the bait and take this off when tight on the fish and can reel the fish all the way to the swivel. At the swivel I have a short leader about 5 feet. The fish is in gaff range and no hand-lining necessary really.
Long leaders have done me well when I first got started though. I guess its just a matter of person preference.. both are effective.
