I'm not sure. I like the look of the Grass, but of course, it has the most weaknesses, of course. I chose Chikorita for HG, though, and it's worked well, so I will definitely choose Grass for either Black or White, it's just a matter of which I'll play first. I don't really like the look of the Fire, and I like the Water even less, but of course, they don't stay in their first form for long. It's too early to decide for certain; I'll have to wait until we get more info about evolutions, secondary types, stats, and moves.
