For any fresh or saltwater species. Caught my PB striper on one this spring. They have a unique swimming action that you have to see to believe. Fish them where you fish any mag darter or SP minnow. This is, by a long shot, the least expensive option on ebay. You get all three for $40. These are better than IMA Sasuke, mag darter, or Aima except their longest is 140 mm and way more expensive.
