If it were me, I wouldn't spend big bucks for a rod you're just going to troll or jig with. For that, get a sturdy cheap rod, and use the extra cash to get a good reel to go with it.

The only application where I prefer an IMX over a GL3 is steelhead drift fishing with light lead, where the extra sensitivity and lighter weight really shine. I think GL3's are a good compromise between the durability of a GL2 and the lightness and sensitivity of an IMX, for most other techniques.

Just my humble opinion.
