B&M corkscrews aren't really painful in my opinion, but not enjoyable. They are different then an Arrow or Vekoma in their desgin. I haven't been on a Vekoma with a corkscrew, but I've heard that Arrow and Vekoma's corkscrews aren't too different from each other. If that's true, then I would say Vekoma would be a bit more enjoyable, (if it's smooth) I've been on smooth Arrow corkscrews that I find them to be very fun.
