When it comes to coaster ratings we usually see "fastest" , "tallest" or "number of inversions". One factor that I don't see very often is "smoothness". I am really curious to know (especially from you Rob Alvey) what coasters really stand out from the rest as to how smooth they are. Although I have not taken a ride on it, there was one reviewed here on TPR that looked like it was very smooth. I can't recall the name of it but it was in Poland.
