Generally, based on where your at, +nin -res results in the strongest setup for her since her self he scales off based nin and it boost your damage since crit benefits from higher base damage. I would only recommend the + life if you have max mood and if your having issues surviving against a blitz teams around your bp and that said teams make up most of the relative players for your level. If your in the stacking stage already survival shouldn't be such an issue assuming you have a good team backing it as well, ideally 7 sword bee since if your the slower player kushina can get a large amount of hp back and the shield will make one shots very rare.
