If all you need is a 5-7" wheel for a sport scale biplane, I think I'd stick with the WB or Dubro wheels. But are you sure you only need this size on a 96" span model? My 63" span Snipe uses a 5" wheel. So if you've got something like a Pup at 96" I'd imagine that you'll need at least a 7" wheel and possibly even larger. There's nothing worse on a WWI model than itty-bitty wheels!
