IMHO the rod's you are listing are not designed to be fished with 4 lb. test. Looked up the 12' ACC it's a mediumn power with " fast tip " . With a rod that stiff I would not fish less than something like Gamma or K-9 in no less than 6 lb. and prefably braid of 8# or better. Spend a little bit more on a high end Japanese braid like Varvias and if needed use a flourocarbon leader, but in my expierance crappie or not line shy if they were the high vis line most of us use would not work. The
AREA Super Trout INFINITY PE x8 – VARIVAS in .3 gou has a break strenth of 7.5 lbs and though a little bit pricey will not behave like American braids in all of the wind knots and wrapping crazy that your probaly used to. That or get some true ultralights again preferably something out of Japan that designed to use light line. Scott
