I've fished with a lot of jig poles over the years, and the Diamond Series is hands down my favorite. I own the 14-foot model for vertical jigging and the 10-foot model for casting, and both have been outstanding. They're lightweight, incredibly sensitive, and still have plenty of backbone when a big crappie decides to fight.
These rods spend more time in my hands than any others during guide trips, and they've held up to daily use without missing a beat. If you're serious about chasing crappie, you won't regret adding one to your lineup.
