Eh, I only use rare candies when I really need to, or when my pokemon is one level away from learning a really effective move. Other than that, I find that if you level your pokemon through natural battling and training, they become stronger and have better stats rather than rare candy training. Plus throwing in some minerals and what-not helps as well. Heck, I always train my pokemon by having them battle against pokemon whom have a type advantage over them, and call me crazy, but I think it actually helps to make them more resistant gradually over the course of their training.
P.S. Shiny pokemon are not better than their brethren. They just wook pwetty. I'd rather have a shiny for a pet than a serious battling companion. Yet a lot of people on these wi-fi battle vids seem to think that shinys are the equivalency to God or something. I'm not saying they're annoying, all I'm saying is, I just don't get the hype.
