I'm a big fan of Fireline. I've spooled up with 4lb./smoke color for years on my ultralight. It's tough to beat the sensitivity (no stretch) and strength. I mostly go after bluegill and crappie, but my biggest fish on the 4lb Fireline was a 6.25 pound walleye caught out of Paintsville Lake. I mainly fish small hair jigs around heavy cover. I've broken off several times, but there have been countless times that I've straightened the hook. My favorite ultralight rod and reel is currently spooled with 2lb. Fireline crystal (supposedly has a 1/2 lb. diameter). I've had great success with it as well. I've hauled in several walleye and catfish on the 2lb. Though its a bit pricey, I'm hooked on Fireline!

Good luck fishin this year!
