but i thought hinata's byakugan wasn't all that developed.. so just because she has it doesn't necessarily mean that she could win against ino.. i reckon they have equal chance of winning. but i must agree with the breast theory.. i mean.. when we were introduced to tsunade.. i was like.. far out! what is the dealio with those breasts? but with sakura and ino i was quite happy that they were drawn like 13-y/o (i.e. relatively flat-chested).
the theory for guys where the more perverted they are.. the stronger they are seems true... but then that makes me wonder how perverted the fourth was... i mean, he was trained by jiraiya as well... gosh! that's ruined my image of him.
