It's actually kinda hard IMO to find the right trout rod for crankbaits and artificials. (such as kastmanster and panther martins etc)
I like the berkley 6' tactix spinning rod myself.. it's made for drop shot and finesse fishing but it's one of the best all around 4lb rods I have tried. Works really great for trout and bass fishing light line. The high modulous provides a lovely action to the light tip. $53.... Walmart.
I just built a pretty nice marbled custom rod I intended to be for bass but it had a bit more moderate action than I would have liked and turned out to be a great panther martin and trout crankbait rod. If anyone is interested in purchasing it let me know. Works great.. got a 17" wild on it the other day for dinner using a rapala CD-5. Rod was bent ina U-shape for two minutes making sure it didn't release the tiny hooks on the crankbait.
