Vaporeon was one of my original favorites too, only it switched with Espeon. xD
I'll go for Umbreon in HG/SS though.
& Well.. I'ved played through about half of Heart Gold on a ROM, and so I really wanna get Soul Silver, but it doesn't have Growlithe. :/ Sooo I plan to get HG, again.. just for that. xD; -sigh-
