Anyone ever used them? I got an 8 pack of 4 inch baits in a lot of tackle I purchased online.

Do these work well or do they fall into the same category as the Storm swimbaits?

Should I keep em or pass em on?

Attached is a pic of the bait next to a Baitcasting reel for size reference

they work great on chesapeake bay stripers

Yeah great striper baits for fishing the surf, I can sure tell you that. I prefer them over the storm swimshads any day. The tail is alot thicker/stronger, unlike the flimsy storm swimshads, making the tsunami swimshads tail swim alot nicer. I also find the tsunami swimshads to ride a little nicer in a straighter position, while the storm swimshads tend to have a unnatural swim, where the head of the bait kinda swims downwards.

I can't tell you how well they work for freshwater bass simply because I've never tryed any of the pre-rigged "swimshad" style baits for freshwater bass. But I can tell you this. I was once fishing at one of my local spots, and seen a guy casting around a pre-rigged swimshad style bait, I forget which brand it was, might of been a storm, and I watched him catch a few bass on it. So, I know they have the ability to catch fish, hope that gives you some confidence, but I personally have never tryed them freshwater.
