I bought the Lightline DT in a 3 weight to go with both my Douglas upstream rod and a bamboo midge rod. I haven't tried it on the bamboo rod yet, but it is perfect on the Upstream 3 wt, which has a bamboo type action. The line has welded loops at both ends, and floats like a cork. There is no sinking of the tip with this line and it casts beautuifully. It is unique in that half of it is tan and half is brown. It is a short line (70' long) but it is not intended for long casts.
