Very possibly my favorite rod. I sometimes fish it with a sink tip as well and have had no problems doing so. I follow the same general procedures which Ted laid out, which I think are appropriate to sink tip lines in general. The one I use is the Rio DC 15, which is a density compensated 15' sinktip. I happen to use the type 6, which has a sink rate of 6"/second, because I use it on a big, fast tailwater, but they also offer a type 3, with a sink rate of 3"/second. Both are available in a WF6, which I found to match that rod just fine.
