Perhaps weak points is not so much the term I need to use rather than limitations. Gear second increases both his strength and speed, but it has an emphasis on speed over strength. Likewise, Gear 3rd focuses on strength at the expense of speed. If he combined the two, he would likely ensure that those limitations wouldn't be as much of a problem. Gear 4th seems to lack these limitations with its short usage being its problem. If he can increase his strength in gear second or his speed in gear third then he won't have to rely on gear four so much since it seems to be an all-or-nothing gamble when he does use it. I would feel more comfortable if he had more options.
