Eh, I actually like the way the whip feels in LoS. I can see what you guys mean about it lacking the "snap" that one would expect though. It's more like you're beating things and enemies with it though, which does make a certain amount of sense. But as I said, I like that. Snapping can work though, as seen in Lament of Innocence.
Actually though, speaking of that, Leon in LoI uses leather whips, a case in which such a tactic makes a lot of sense. In Mirror of Fate, Simon is supposed to use a leather Vampire Killer whip. I wonder if he will use snap-oriented attacks like Leon. That would certainly make the Simon feel different from Trevor. But who knows?
ALSO: MoF takes place 25 years after LoS. I wonder if they'll crack a joke like Nintendo did with Zelda and make an anniversary joke. Something about it being the "25th anniversary since the first appearance of Dracula" or something.

It is the 25th Anniversary for Castlevania after all.
