A couple of years ago, when the soft swim baits first became widely available (in MO), I bought several different brands. No let me rephrase that, every tackle store I went into, if they had a brand I didn't have I'd buy several. If they only had brands I already had but had different colors, I'd buy that.
I'd describe my results as mixed. The Strike King 6" Shadalicious (chartreuse shad) attracted the largest fish I'd ever seen in one particular lake, but it didn't hit. It just followed the bait for 10 - 15 feet or so and then just lazily swam away. That same day I caught several 18 & 19 inch fish on that bait.
My plan was just to throw it as far as I could (17 lb fluourcarbon) and swim it back. If I could see it real good, I figured it was too shallow. If I couldn't see it at all, then that was too deep.
This was in pretty clear, shallow to medium depth water (3 -8 ft). I was never able to duplicate this, so after several trips, while I would have a swim bait rod rigged in my boat, I didn't throw them all that often.
Last year, similar results - a few fish but nothing outstanding.
Reading In-Fisherman magazine, the primary editor Doug Stange, writes that his most productive swimbait style bait, by far, over the past few years, was the 5" Berkley Powerbait Saltwater Swim Shad, fished on 1/2 or 3/4 ounce jig heads. I bought some of those, that's still a work in progress, except I haven't had the kind of results that Doug Stange writes that he's had.
Fast forward to earlier today, I spent up all my Cabelas points and got 4 packs of the Sebile soft magic swimmers. We'll see how those work. They are a little over 5" long and they weigh 3/4 ounce according to the catalog.
My initial plan is to throw them using a 7' MH spinning rod, 14 lb fireline and a 15 or 20 lb fluorocarbon leader. I recently got a decent deal on a US reel Supercaster 240
($50 from Rogers Lures in Liberty, MO) so that's the reel I'll start with
I think the deal with swim baits is that you need fairly clear water (3 or more ft of visibility) and that doesn't always happen on the smaller conservation lakes I normally fish.
