Anyone have either of these two models? Looking for a six pound line rod: light tip (eggs/bait) with a little backbone.

No, I just bought a Shimano in that size. Have caught up to 3-lb bass on it on 6-lb line, with a 1/16 oz jig head and a 2-inch grub.

Barrons in Columbia stocks a wide variety of Loomis.
Look at the St. Croix rods at Dick Sports.
