Which C5 are you planning on buying? Each one is a little different. Also depends on what you are going to be fishing with/for. If it is soley a bass rod and you plan on using things like jigs/worms/other soft plastics then I would go with a 7foot med to med/heavy rod. Personally I prefer a 6'8" (mine are specially made) medium action casting rod. This is pretty much just because the fight is more fun.
