Sorry to dig this up, but just to comment. Titan and Goliath are almost clones, with just two differences. Titan goes up higher, but the two drops (and thus, the heights/dimensions/layout) are the same following. The other difference is the "bonus helix" found on Titan, just after the airtime hill, leading into the MCBR. This adds the extra length to Titan's stats, and also those additional crushing Gs that Goliath lacked on your rides. So experience-wise, they are certainly not clones, even though their layouts are in fact nearly identical.
And to add to something a bit more recent, Carowinds has jumped the bandwagon and announced the removal of their log flume, further showing how fortunate KI is to have more than one splashing water ride.
Wait, does the Coca-Cola Oasis count as a perpetually splashing attraction?
And for 2010 Carowinds is rumored to also get a B&M hyper... but lightning never strikes twice...
