Let me tell you how this all started, and then you might see where I'm going. This last year, I was casting for crappie with a #3 Mepps Aglia, a fairly reliable crappie-getter. One of the guys I fish with was using a #5 Aglia, going for bass. He caught a crappie. No snag or anything; the crappie bit the hook. I must have looked incredulous, because he laughed and said, "Yeah, it happens sometimes. Crappie sometimes go for big lures, y'know." Well, no, I hadn't known they hit something THAT big. So we got to talking, and he said that there were slews of 3/8 crankbaits and spoons that are good crappie lures. (I think he said that because he knew that I love to use spoons.) So I got out some 1/3 and 3/8 oz. lures (ones that he thought might be productive for crappie) and put them on my smallmouth rod. It's a ML/F that had 8 lb. line on it at the time. I might have caught one or two crappie that morning, but the rest of the time was pure frustration. I'd think I got a hit, but .... no fish. I thought I could feel what was going on, but .... nope. Dead feel. So I took the reel with 4 lb. line off my ultralight, and put it on the medium light. Heck, yeah! Now I could feel what was happening, and I started to hook crappie again. But that day, I threw two lures away because the line snapped. I can't remember both, but one was a 3/8 oz. silver spoon. I noticed that the 4 lb. line gave me a LOT better feel with that (or any other) spoon compared to the 8 lb. line. Later I tried 6 lb. line, and I had some luck, but could still feel the lure better with 4 lb. line. So I figured would use 4 lb. for as much as I could, only moving up to 6 or 8 when I absolutely HAD to. I know that this rod is a lot different than the ultralight I was using, and stresses the line more. But if I can feel what's going on, I can hook fish better with this rod than the ultralight. Faster reaction time on my part, I guess. I want to use 4 lb. with 1/3 ounce Cleo spoons for sure, and 5/16 Bomber A4 crankbaits, too. But I don't have any idea how much further I can push it, and whether the stress I'd put on the 4 lb. line increased the chances of it snapping like it did. I feel comfortable predicting how 8, 10 or 12 lb. line is going to act. I am far less confident when talking about 4 lb. line. Now you, Team9nine, said "... unless you're trying to wing something crazy in weight for 4 lb. line ... " What's a crazy weight? Where should I stop? From what I've always seen, crappie in fall hit a bigger set of lures than crappie in spring. They all taste great, though! jj
