^no, I believe snivy is the best starter for this gen. I luckily got contrary as its ability. Now I'm focusing on train its speed to max while balancing its def and sp.def. I'll Let the leaf storm and draco meteor do the bussiness later.
And yeah, brawly's machop have a well trained EVs spread. I got my arse beaten as well. But the rest of his team are no big deal.
And yeah the file size are almost half of the BW2 roms I have. But the quality stay the same, I suppose.
