Well, I am a pretty big fan of vaporeon myself, I at this point I would have to say that the groweon is a very useful set, and I feel its hazing capabilities, while decent, are limited to a certain degree by an onslaught by say a curselax, who with double edge could just plow right through the defenses nonetheless, and although I have an impressive amount of luck, and although your attracting/hazing vaporeon is good in theory, I really do not like to leave things up to the roll of the dice when it comes to attraction.
anyway, the set I use currently;
vaporeon@mint berry
growth
surf
ice beam
rest
