I used to fish rods in the $100-200 dollar range exclusively for years. The first time I had a custom Kistler Z-bone jig rod built, it changed everything for me. Now I have 5.
I still use rods in the $100-200 dollar range, but for different things. In that range, the Kistler KLX is the best I have found.
I use the mid-priced KLX for Frogs, Cranks, spinnerbaits, chatterbaits, topwater.
I use the high end Z-bones for Jigs, T-rigs, Senkos, shakey heads, drop shot.
I am extremely happy with the balance points on the KLX for rods in this price range. Other brands in this range can sometimes be tip heavy. Split grips just makes that situation worse. I prefer full cork rear, no front. That was the motivation behind my first custom z.
The Z's are just crazy light, they are made with Gary Loomis's top end blanks (which can be bought raw from NFC). And yes, they are impressively sensitive. Other guys who have used my rods while fishing with me have realized there is a certain learning curve due to the fact that no matter what line they used, they were false hook setting on all kinds of stuff that they didn't distinguish between with their other rods. Not that they didn't feel something there, its just that the ability to detect sudtle movements was intensified with the z's and they mistook those feelings for bites. You begin to develop the ability to read the bottom like sonar. Distinguishing between bottom compositions, debris, and actual fish. I was able to do this somewhat before, but it really dials you in with a light, sensitive, balanced rod. However, this takes time with your rod. You really notice it when you go back to a lower end rod. Also, due to the lack of fiberglass in the blank, the way the rod loads just has to be experienced to appreciate. I remember talking to Lance, Kistler's rod builder, and the best way he could describe it was that it has a crisp and responsive feel that isn't found in other rods. That's about right on the money.
I used to attach and epoxy balance kits to rods, but I stopped doing that. The whole rod got heavier and all I was doing was trying to turn an average rod into a really good rod. If you buy a really good rod, chances are it will be balanced right, or you should shop around for one that is. I know a lot of guys say that a rod feels lighter in the hand when it is balanced, which is true when initially picking it up. But bottom line is you still have to hold that rod up in the air. Adding 2 ozs of brass weights to a rod is just 2 more ounces you have to hold up. I learned this lesson backpacking. No matter how well distributed your gear is (which is important), you still have to carry it all. Makes you think about what is really necessary weight wise.
My advice would be start a savings envelope, find a high end rod price to shoot for, and get cracking. If you spend time with that rod, I don't think you will ever feel it was a waste of money.
