In rough conditions, the Nuance does penetrate better and is a little easier to deal with in high winds. The BiSide flies awesome though, but can be a little more work on a nasty day. They both fly great. The BiSide presents larger, but I wouldn't say better, just different. There is definitely a group that prefers the look of monoplanes, versus biplanes. The other thing is you have two wings to give away when you are level or not. Not trying to talk you into one or the other, just giving you feedback with tons of flights on a Nuance (2012 Masters NATS Champ with it) and many flights on the BiSide. For the lower classes the BiSide can be a little more work to accomplish the same thing when conditions aren't perfect.
