The funny thing is that of the ones I have ridden (Adventure World, Kentucky Kingdom, Canada's Wonderland, Darien Lake, and Geauga Lake), it seems that the ones with the longer trains...the 10-car versions...seem to run better than the ones with the shorter trains. Honestly, I haven't studied it enough to say what the real difference is...but it's a dissenting opinion, anyway. Personally, I think that of the ones I have ridden, Geauga Lake's is the best and Kentucky Kingdom's is the worst...although Kentucky Kingdom's is dramatically improved since the season it opened.
