Catching Raikou and Entei has been such a bitch. I almost had Raikou, but he escaped the ball at the very last second and then used Roar to end the battle and I haven't gotten close since then.
I already got my 16 badges and now I'm just trying to catch as many pokemon as possible. Leveling up is easy now, all I do is go and beat the Elite Four over and over, I'm trying to level up enough to beat Red, I tried taking him on once and I got past his Pikachu barely, and I couldn't get past his Lapras.
My team right now is:
Feraligatr, Lv. 71
Ho-Oh, Lv. 56
Lugia, Lv. 74
Dragonite, Lv. 58
Donphan, Lv. 52
Jolteon, Lv. 49
