This seems to be the consensus, but I disagree. I find the Vekoma seats to be much more comfortable. The B&M restraints feel very bulky and fairly uncomfortable. I much prefer the clasping vest on the Vekomas.
Sorry I should have stated, I haven't been on a Vekmoa flying coaster. I've been on a B&M though and I was comfortable. I will compare when I go to Kings Island.
