The random groupings is definitely where Mitch Hawker's poll falls down. Not only does it unfairly bias groups with fairly equal coasters higher on the list than they would otherwise be (i.e. B:TR Clones, standard SLCs) but the varying groups such as Wild Mice cannot be accurately reflected with just one listing. I've got 76 coasters separating my favourite and my least favourite wild mouse, so it's very difficult to accurately reflect that.
I really don't understand either why Mitch Hawker just doesn't sit down one evening with rcdb and properly update his poll with the countless rides he doesn't have, not mention splitting out the XC2000/3000 coasters which contain several different rides, which should not be lumped together at all.
Anyway, mine both done now, Dueling Dragons: Fire still my favourite steel, but I'm determined that it shall be its last year at the top. Grand National my favourite woodie, long may that reign though!
