You'll never get a good, basic, unbiased answer on this type of question.
Just a bunch of fish geeks spouting off their own personal opinions and prejudices.
I am about to be one of them.
The best way that I feel in a longer tank is to have a canister filter and a HOB filter. The bio-wheel 350 is a good place to start for sure. Couple it with a Fluval 205 or a Rena XP2 and you'll be in darn good business. The reasons for using two filters are several - one, because you have a back-up filter to protect against the small, but significant chance of one filter failing. Two, because it will cut down on dead-spots where the water isn't flowing efficiently through the tank. Three, because you can maintenance them on a rotating schedule and virtually guarantee that no matter how much you mess up your bio-media in one filter, the other one will cover your butt. Four...because it just makes a nicer, healthier tank.
