I got in the new Rio Premier technical trout double taper 4 weight floating line and wanted to do a review. I previously had on the Rio select trout premiere floating line and decided to try out a double taper for the first time . The new technical trout double taper line was OK at best. It did not perform anywhere near what the select trout premier floating line does. I gave it several times out on the water but always ended up in frustration. I could not keep the loop open or drop a small dry without piling up in the water ahead of me. The DT line seems stiff and has a bad habit of taking a set memory being on the spool. The line starts out really thin and gains diameter pretty far back and just wouldn’t work with my Sage VXP or ZAxis. Don’t really understand it but for $119 it was lack luster. Just took it off and put the old line back on the Galvin Torque I mainly use. The Select Trout premier line is a few seasons old and works awesome, just thought the new DT might be a step up. It will be used for nymphing if it can do that.
