It is a narrow boat and feels it.  The Viper, Probes, Prodigy X, Nitro and most others are wider.  I have not been in the Viper enough to give a real opinon of it.  Many like the probes and Prodigies.  The nitro is fun as well.  Outfitting is key, low as possible and try to keep it comfortable.  us big guys can put a lot of weight above the gunnels and that makes for tippy.
