The 3.0 is still 3" long -- hence the name. Might be a bit big for stocker fishing. But for a plug that size, they dive deep and fast. Much better than the K9, which it's similar in size to.
And there's a catch with the 3.0 -- very hard to get. There was some production problem or something. My buddy bought 2 at the Sportsman's Show, which is all they had left. So naturally, last week we tried them out. Funny, we so rarely lose a plug while backtrolling, and lost one of the 2 immediately. I'm sure if it was one that could have been replaced, it wouldn't have hung up beyond hope.
And we didn't touch a fish that day. He went yesterday, and caught one on the remaining 3.0 while letting it run out with less than 20' showing on the line counter.
