In addition.... I'm not a huge fan of the Nouveau sets (just personal preference)
Also, if you're a fan of bigger toms, the YESS mounting system can soak up a little low end. I'd suggest checking out standard floor toms with legs rather than the mounted toms if you're using 15"-16" drums.
All the top of the range Yamahas are great drums though, and you wouldn't be making a mistake buying any particular range over another.
