Thanks for the info people. It sounds like many different varieties of leader will work. Anything from 10' , treble hook wrapped in lead with a little of the ole Toutle River Jerk applied, to a 2 or 3 foot job. I think when it all comes down to it, presentation may be a key factor. I think I'll split the difference and try a 6' leader and see how I do. If that doesn't work maybe I'll try some of this...
