Apparently nothing else in your eyes. The blank is only part of the equation. While they are nice there are still many companies offering very nice rod lines around $200. MB Levante, Dobyns Champion when on sale, Phenix Recon, Avids and the list goes on.
When you say complete rod lines how many rods are you looking for? You only mention about 4 rods but when I see "complete rod lines" I think of many more techniques. The Dobyns Champion line has everything covered from punching, to swimbaits, to finesse. You won't find that kind of diversity in the KLX series.
