im curious, im considering buying a squat suit, but i have some questions. first off, do suits actually get you any gains on you squat/deadlift, or do they just make sure you have nice form? second, what would be better, a champion suit or a z-suit? can anybody guesstimate what i might be able to hit in a suit if i can hit 425 on squat with just a belt?

thanks in advance.
