lol, the reason is that most of them are bold on the simulator, and it one im running is timid. So far i have decided on max hit points and 88 speed evs, which outruns the fastest users of +1 priorety, not counting stupid stuff like quick attack swellow. (also, running so much speed means i can taunt opposing whimiscott).
I have 160 Evs to spare. Max def is an interesting idea, but the cool thing about grass is that it resists water and electric, which is something i'd take advantage of, if possible.
basically, im a dork, and pokemon requires too much math
