I rode saw today and maybe it's just the novelty, it didn't completely blow me away like stealth did but that is because I was not an enthusiast when stealth came out. Also, saw is not a one trick pony. Stealth has quick launch, one good drop, brakes. Saw is almost 2 rides, a dark ride and then a thrilling ride in one. The airtime on the dark drop, the 95* drop, the hill and especiall the drop out of the MCBR are awesome.
That said, Oblivion, although a one trick pony is one of my favourite rides ever as well. I still think saw is the best ride overall at thorpe, but I'll just have to wait a few weeks as see what I think then.
