While I like the SA Mastery Bass Bug line, too (I use their Wet Tip sinking tip lines), I'll put in a vote for the Rio Clouser line. I use one on my Scott A2 906/4 for white bass and small mouth (and light largemouth) for chunking big streamers and topwater and I REALLY like it. I used it all last year. It's also a decent nymph line if you throw a big weighted nymph and/or some split shot.

The six-weight is the only weight I've tried (I have the SA Mastery Bass Bug on my 8 weight Scott SAS), but I plan to put one on my 8-weight when the SA wears out, even though I like the SA, too.
