Friday, I went to my favorite fishing hole to catch a few stocker trout. My reels were strung with 4 pound Stren mono line. The same line I have used with success for years. Well, this past trip I hooked into something (guessed over 6 lbs) that surprised me and with the 4 pound line, I never had any control or chance to land this fish where he ended up. I played him for about 10 minutes and the drag was working fine. He just headed into some brush and broke me off. I looked at Bass Pro's Website and the diameter of Stren Monofilament line is .008 in 4 pound test. I looked at some of the braided lines and could get in the 10 to 12 pound test range with a .006 diameter. A thin line with more strenght. Do any of you used braid lines for trout, and if so, what test? Are there any problems with braided lines that I can expect? Knot strenght, cold weather fishing, memory? Thanks in advance for any help.
