The Rapala rod looks like a bit of a copy of the Shimano Blue Rose series. I guess Rapala are really trading on their name and the rod will sell because it's cheap, not because it's got a respected pedigree or such like.
If you want to see what a class jig rod looks like check out a Blue Rose or better yet something like Smith 55Niraii you won't be disappointed.
Of course big schools of hungry or spawning fish make life easy for us jiggers, any old rod, jig and technique will more often than not get results. Move away from that senario and things change, you really see the cream rising to the top. The jiggers with the good stuff, the gear that's been researched and tested and refined will catch more. This is the incentive to buy better, in the long run the gear will be more satisfying to use and own.
