Nothing wrong with bio-balls, been using them since the early 90's with great results. If you want a FO tank then keep them. If you want to go to the reef side with anemone's or anything else along those lines then ditch the w/d & make the w/d a fuge. It really depends on what you want to do.
I have been setting up my 475g & I was going to go the LR route with a refugium & all that. I was told by several shops/installers to stick with a w/d due to the fish I like to keep. I was also told to do a deep sand filter to keep the nitrates down. I will add one to my tank one of these days.
LR gets expensive & you can't or shouldn't put copper in the tank.

I also started in 91 first with bio bale and then moved to bio balls. My 200 was set up for 10 years before I moved up to my 300 and Nitrates stayed below 5 with a bunch of fish. I have always been a big believer in trickle filters. I also have a fuge with rubble and chaeto that dumps into a large open sand bed refugium. It has been a month since I did a water change and my nitrates yesterday where at 1 to 2. If you have a lot of trash in your tank then keep a filter pad in the tray over the bio balls to keep them clean.
