Ok good point.. (or points..) but not curvy makes me straight go to er well .. straight!
Tricky to only use a few words though. I would have said no variation in height, but that might be a bit long. or 1-dimensional but that might make people think of all sorts of other things. Still feels better than not curvy though, but that is just my opinion.
