Lenny - I have not used them yet but they seem priced right. I also didn't meet #^&#^&#^&#^&#^&#^&#^&#^&#^&#^&#^& until late fall when the fish had moved on...
Beyond that, using the lures depend on a lot of different things - even something as simple as a needle fish is worked differently depending on the brand and even model. A gibbs stubby is often worked different than say a habs or a boones or Tattoo and so forth. Some float, some sink, some sink fast, some sink fast ass-end first, some hover near neutral... So there are a lot of variations - each using a different way to be worked. Then you factor in wind, dropper no dropper, current, and it all adds up
I'm sure #^&#^&#^&#^&#^&#^&#^&#^&#^&#^&#^& can add some points on how his work but again I have not used them personally - although I intend to check them out this year...
