I fail to see how a dive machine could even be compared to Maverick and Top Thrill Dragster. Maverick is beyond vertical, and the drop is over almost before it's started. Top Thrill Dragster's drop is ruined by the twist. A dive machine is 90* for quite a while, and has a holding brake at the top. It would be a completely different experience.
Also, Even though a flyer, and aqua trax, and a dive machine(arguably) are the only three types of unique coasters CP doesn't have, what about a nice wooden coaster? The last wooden coaster that CP built is now eighteen years old, and **** streak sucks! Blue Streak, as classic as it is, isn't anything special. A nice GCI twister or a GG airtime machine like RFII, would be a nice addition, especially with Millennium Flyers or even Timberliner trains.
Lastly, I've said this before, and I'll say it again. After riding El Toro, I find it even more retarded that even though CP has been in bed with Intamin for a decade, they refuse to build a plug n' play.
