I generally use Rio's SlickShooter in 25# for almost everything these days.

Though for my trout fishing in our cooler current Montana conditions, I find myself using the Rio's Connectcore in .026.

Monofilament tends to get a bit wire-like under 35 degrees or so making the pvc line a little easier to handle with trout retrieve techniques.

If I was unconcerned about retrieval and just fishing a straight swing, mono would get the nod irrespective of temperature.

While I know of a few individuals who use the Stren Catfish line, I don't have plans for it myself.

Happy Holidays to you and yours Bill.

My best,
Mike McCune
