Do you love big bluegill?
I got some hi-viz yellow #4, but I am afraid it will spook the fish.
Have been using Trilene XT solar for quite a few yrs now. Sadly they discontinued making it in small diameters, but I picked up some on e-bay. Most of my gill fishing is with crickets on the bottom. You can see the slightest tick with this line. I really believe it helps me.
I use high viz yellow braid. Works fine. However, I do use in conjunction with a flouro leader between 12" to 30", depending on the depth I'm attacking. Shallower the depth, the longer the leader.
Years ago I used Stren Hi Vis blue for bass fishing and we caught lots of bass. Recently the Crappie did't seem to mind it tied directly to a jig, but I was fishing down about 12 feet. I'm going to try some Hi Vis Vicious this spring on Bluegills and Redears. We'll see if they hit better with or without a flour leader. I hope that I can tie directly to the spoons and jigs...
I usually use 4 pound suffix hi vis yellow mono. I never have any problems catching fish. I like the idea of seeing the line, especially if a lite biting crappie takes off with the jig. Also, Mr. Crappie, Wally Marshal uses hi vis line. I seen it in some of his videos where he is shooting docks for crappie. Before, you ask, shooting docks is where you let about 4-5 feet of line out, and you grab your jig and pull the jig under your rod past your reel and you sling shot your jig under the docks. I think you will like seeing your line, and you will not have losses in the amount of fish you will catch. I am not a fan of Viscious though, I think thier line is very cheap. and their plastics are worse. I swore I would never buy another product from viscious because their products suck.
