Most of the rods already mentioned are great and will do the job for you. I'm currently using 3 models of panfish/crappie rods from B n' M. Can't say I like one over the other though. For float fishing I prefer the longer 9' SHSS and/or the "Difference" in 9' length. I think it will boil down to what you feel most comfortable using.
I will tell you this though. If I had only one rod model to choose, it'd definitely be the B n' M, 7' SHSS. This wonderful rod can/will do anything you want. And it's tough enough to handle bass as well, should the occasion arise. A tad more expensive than a lot of those previously mentioned, but they are worth every penny. JMO.
