I guess I haven't worked it particularly well. But here's the thing, I've had two rides on Grand National and they were not at all 'rough'. From my experience, I genuinely cannot see why people would call it rough, for example. Perhaps I was just lucky.
Could say something similar for my first ride on Goudrix. It was great, if a little intense. But nowhere near as rough or uncomfortable as people described. So again, from my experience, I genuinely could not see where the hate comes from.
That was until my second ride, where I had a complete opposite experience.
I can only go off my experiences. Me saying "I don't get the hate" for a ride isn't to invalidate the experiences of others. Obviously people do hate it and have their reasons, and some ride it incredibly rough. Fair enough. But simply, my (limited) experience doesn't help me understand why people do hate it as much as they do.
