I have to second the Tatula suggestions. I have two of the 7'1 MH XF rods and I love them. One is for texas rig and jigs, and the other is for carolina rig. Now, I will admit I have not used many other rods in that price range to compare it to, but I have noticed the Tatula to be extremely sensitive. I also love the ergonomics of it. 

I do not have any experiance with the Shimano Crucial, but I have used the Clarus and the Compre line of rods that Shimano puts out. If I were to go back before I settled on the Tatula knowing what I do now, I would have looked into the Crucial as well. I doubt you would go wrong with either.

I like the st croix avid for that price. I've owned a few for a long time and have been pleased with them. I'm in the process of upgrading now and am having a hard time thinking about parting with them. Good warranty as well.
